# Citation Quality Checklist
Use this checklist to ensure your citations are accurate, complete, and properly formatted before final submission.
## Pre-Submission Checklist
### ✓ Metadata Accuracy
- [ ] All author names are correct and properly formatted
- [ ] Article titles match the actual publication
- [ ] Journal/conference names are complete (not abbreviated unless required)
- [ ] Publication years are accurate
- [ ] Volume and issue numbers are correct
- [ ] Page ranges are accurate
### ✓ Required Fields
- [ ] All @article entries have: author, title, journal, year
- [ ] All @book entries have: author/editor, title, publisher, year
- [ ] All @inproceedings entries have: author, title, booktitle, year
- [ ] Modern papers (2000+) include DOI when available
- [ ] All entries have unique citation keys
### ✓ DOI Verification
- [ ] All DOIs are properly formatted (10.XXXX/...)
- [ ] DOIs resolve correctly to the article
- [ ] No DOI prefix in the BibTeX field (no "doi:" or "https://doi.org/")
- [ ] Metadata from CrossRef matches your BibTeX entry
- [ ] Run: `python scripts/validate_citations.py references.bib --check-dois`
### ✓ Formatting Consistency
- [ ] Page ranges use double hyphen (--) not single (-)
- [ ] No "pp." prefix in pages field
- [ ] Author names use "and" separator (not semicolon or ampersand)
- [ ] Capitalization protected in titles ({AlphaFold}, {CRISPR}, etc.)
- [ ] Month names use standard abbreviations if included
- [ ] Citation keys follow consistent format
### ✓ Duplicate Detection
- [ ] No duplicate DOIs in bibliography
- [ ] No duplicate citation keys
- [ ] No near-duplicate titles
- [ ] Preprints updated to published versions when available
- [ ] Run: `python scripts/validate_citations.py references.bib`
### ✓ Special Characters
- [ ] Accented characters properly formatted (e.g., {\"u} for ü)
- [ ] Mathematical symbols use LaTeX commands
- [ ] Chemical formulas properly formatted
- [ ] No unescaped special characters (%, &, $, #, etc.)
### ✓ BibTeX Syntax
- [ ] All entries have balanced braces {}
- [ ] Fields separated by commas
- [ ] No comma after last field in each entry
- [ ] Valid entry types (@article, @book, etc.)
- [ ] Run: `python scripts/validate_citations.py references.bib`
### ✓ File Organization
- [ ] Bibliography sorted in logical order (by year, author, or key)
- [ ] Consistent formatting throughout
- [ ] No formatting inconsistencies between entries
- [ ] Run: `python scripts/format_bibtex.py references.bib --sort year`
## Automated Validation
### Step 1: Format and Clean
```bash
python scripts/format_bibtex.py references.bib \
--deduplicate \
--sort year \
--descending \
--output clean_references.bib
```
**What this does**:
- Removes duplicates
- Standardizes formatting
- Fixes common issues (page ranges, DOI format, etc.)
- Sorts by year (newest first)
### Step 2: Validate
```bash
python scripts/validate_citations.py clean_references.bib \
--check-dois \
--report validation_report.json \
--verbose
```
**What this does**:
- Checks required fields
- Verifies DOIs resolve
- Detects duplicates
- Validates syntax
- Generates detailed report
### Step 3: Review Report
```bash
cat validation_report.json
```
**Address any**:
- **Errors**: Must fix (missing fields, broken DOIs, syntax errors)
- **Warnings**: Should fix (missing recommended fields, formatting issues)
- **Duplicates**: Remove or consolidate
### Step 4: Final Check
```bash
python scripts/validate_citations.py clean_references.bib --verbose
```
**Goal**: Zero errors, minimal warnings
## Manual Review Checklist
### Critical Citations (Top 10-20 Most Important)
For your most important citations, manually verify:
- [ ] Visit DOI link and confirm it's the correct article
- [ ] Check author names against the actual publication
- [ ] Verify year matches publication date
- [ ] Confirm journal/conference name is correct
- [ ] Check that volume/pages match
### Common Issues to Watch For
**Missing Information**:
- [ ] No DOI for papers published after 2000
- [ ] Missing volume or page numbers for journal articles
- [ ] Missing publisher for books
- [ ] Missing conference location for proceedings
**Formatting Errors**:
- [ ] Single hyphen in page ranges (123-145 → 123--145)
- [ ] Ampersands in author lists (Smith & Jones → Smith and Jones)
- [ ] Unprotected acronyms in titles (DNA → {DNA})
- [ ] DOI includes URL prefix (https://doi.org/10.xxx → 10.xxx)
**Metadata Mismatches**:
- [ ] Author names differ from publication
- [ ] Year is online-first instead of print publication
- [ ] Journal name abbreviated when it should be full
- [ ] Volume/issue numbers swapped
**Duplicates**:
- [ ] Same paper cited with different citation keys
- [ ] Preprint and published version both cited
- [ ] Conference paper and journal version both cited
## Field-Specific Checks
### Biomedical Sciences
- [ ] PubMed Central ID (PMCID) included when available
- [ ] MeSH terms appropriate (if using)
- [ ] Clinical trial registration number included (if applicable)
- [ ] All references to treatments/drugs accurately cited
### Computer Science
- [ ] arXiv ID included for preprints
- [ ] Conference proceedings properly cited (not just "NeurIPS")

- [ ] GitHub links stable and permanent
### General Sciences
- [ ] Data availability statements properly cited
- [ ] Retracted papers identified and removed
- [ ] Preprints checked for published versions
- [ ] Supplementary materials referenced if critical
## Final Pre-Submission Steps
### 1 Week Before Submission

- [ ] Manually verify top 10-20 most important citations
- [ ] Check for any retracted papers
### 3 Days Before Submission
- [ ] Re-run validation after any manual edits
- [ ] Ensure all in-text citations have corresponding bibliography entries
- [ ] Ensure all bibliography entries are cited in text
- [ ] Check citation style matches journal requirements
### 1 Day Before Submission
- [ ] Final validation check
- [ ] LaTeX compilation successful with no warnings
- [ ] PDF renders all citations correctly
- [ ] Bibliography appears in correct format
- [ ] No placeholder citations (Smith et al. XXXX)
### Submission Day
- [ ] One final validation run
- [ ] No last-minute edits without re-validation
- [ ] Bibliography file included in submission package
- [ ] Figures/tables referenced in text match bibliography
## Quality Metrics
### Excellent Bibliography
- ✓ 100% of entries have DOIs (for modern papers)
- ✓ Zero validation errors
- ✓ Zero missing required fields
- ✓ Zero broken DOIs
- ✓ Zero duplicates
- ✓ Consistent formatting throughout
- ✓ All citations manually spot-checked
### Acceptable Bibliography
- ✓ 90%+ of modern entries have DOIs
- ✓ Zero high-severity errors

- ✓ Key citations manually verified
- ✓ Compilation succeeds without errors
### Needs Improvement
- ✗ Missing DOIs for recent papers
- ✗ High-severity validation errors
- ✗ Broken or incorrect DOIs
- ✗ Duplicate entries
- ✗ Inconsistent formatting
- ✗ Compilation warnings or errors
## Emergency Fixes
If you discover issues at the last minute:
### Broken DOI
```bash
# Find correct DOI
# Option 1: Search CrossRef
# https://www.crossref.org/
# Option 2: Search on publisher website
# Option 3: Google Scholar
# Re-extract metadata
python scripts/extract_metadata.py --doi CORRECT_DOI
```
### Missing Information
```bash
# Extract from DOI
python scripts/extract_metadata.py --doi 10.xxxx/yyyy
# Or from PMID (biomedical)
python scripts/extract_metadata.py --pmid 12345678
# Or from arXiv
python scripts/extract_metadata.py --arxiv 2103.12345
```
### Duplicate Entries
```bash
# Auto-remove duplicates
python scripts/format_bibtex.py references.bib \
--deduplicate \
--output fixed_references.bib
```
### Formatting Errors
```bash
# Auto-fix common issues
python scripts/format_bibtex.py references.bib \
--output fixed_references.bib
# Then validate
python scripts/validate_citations.py fixed_references.bib
```
## Long-Term Best Practices
### During Research
- [ ] Add citations to bibliography file as you find them
- [ ] Extract metadata immediately using DOI
- [ ] Validate after every 10-20 additions
- [ ] Keep bibliography file under version control
### During Writing
- [ ] Cite as you write
- [ ] Use consistent citation keys
- [ ] Don't delay adding references
- [ ] Validate weekly
### Before Submission
- [ ] Allow 2-3 days for citation cleanup
- [ ] Don't wait until the last day
- [ ] Automate what you can
- [ ] Manually verify critical citations
## Tool Quick Reference
### Extract Metadata
```bash
# From DOI
python scripts/doi_to_bibtex.py 10.1038/nature12345

--doi 10.1038/nature12345 \
--pmid 12345678 \
--arxiv 2103.12345 \
--output references.bib
```
### Validate
```bash
# Basic validation
python scripts/validate_citations.py references.bib
# With DOI checking (slow but thorough)
python scripts/validate_citations.py references.bib --check-dois
# Generate report
python scripts/validate_citations.py references.bib \
--report validation.json \
--verbose
```

url = {https://example.com/page},
year = {2024},
note = {Accessed: 2024-01-15}
}
```
## Formatting Rules
### Citation Keys
**Convention**: `FirstAuthorYEARkeyword`
**Examples**:
```bibtex
Smith2024protein
Doe2023machine
JohnsonWilliams2024cancer % Multiple authors, no space
NatureEditorial2024 % No author, use publication
WHO2024guidelines % Organization author
```
**Rules**:
- Alphanumeric plus: `-`, `_`, `.`, `:`
- No spaces
- Case-sensitive
- Unique within file
- Descriptive
**Avoid**:
- Special characters: `@`, `#`, `&`, `%`, `$`
- Spaces: use CamelCase or underscores
- Starting with numbers: `2024Smith` (some systems disallow)
### Author Names
**Recommended format**: `Last, First Middle`
**Single author**:
```bibtex
author = {Smith, John}
author = {Smith, John A.}
author = {Smith, John Andrew}
```
**Multiple authors** - separate with `and`:
```bibtex
author = {Smith, John and Doe, Jane}
author = {Smith, John A. and Doe, Jane M. and Johnson, Mary L.}
```
**Many authors** (10+):
```bibtex
author = {Smith, John and Doe, Jane and Johnson, Mary and others}
```
**Special cases**:
```bibtex
% Suffix (Jr., III, etc.)
author = {King, Jr., Martin Luther}
% Organization as author
author = {{World Health Organization}}
% Note: Double braces keep as single entity
% Multiple surnames
author = {Garc{\'i}a-Mart{\'i}nez, Jos{\'e}}
% Particles (van, von, de, etc.)
author = {van der Waals, Johannes}
author = {de Broglie, Louis}
```
**Wrong formats** (don't use):
```bibtex
author = {Smith, J.; Doe, J.} % Semicolons (wrong)
author = {Smith, J., Doe, J.} % Commas (wrong)
author = {Smith, J. & Doe, J.} % Ampersand (wrong)
author = {Smith J} % No comma
```
### Title Capitalization
**Protect capitalization** with braces:
```bibtex
% Proper nouns, acronyms, formulas
title = {{AlphaFold}: Protein Structure Prediction}
title = {Machine Learning for {DNA} Sequencing}
title = {The {Ising} Model in Statistical Physics}
title = {{CRISPR-Cas9} Gene Editing Technology}
```
**Reason**: Citation styles may change capitalization. Braces protect.
**Examples**:
```bibtex
% Good
title = {Advances in {COVID-19} Treatment}
title = {Using {Python} for Data Analysis}
title = {The {AlphaFold} Protein Structure Database}
% Will be lowercase in title case styles
title = {Advances in COVID-19 Treatment} % covid-19
title = {Using Python for Data Analysis} % python
```
**Whole title protection** (rarely needed):
```bibtex
title = {{This Entire Title Keeps Its Capitalization}}
```
### Page Ranges
**Use en-dash** (double hyphen `--`):
```bibtex
pages = {123--145} % Correct
pages = {1234--1256} % Correct
pages = {e0123456} % Article ID (PLOS, etc.)
pages = {123} % Single page
```
**Wrong**:
```bibtex
pages = {123-145} % Single hyphen (don't use)
pages = {pp. 123-145} % "pp." not needed
pages = {123–145} % Unicode en-dash (may cause issues)
```
### Month Names
**Use three-letter abbreviations** (unquoted):
```bibtex
month = jan
month = feb
month = mar
month = apr
month = may
month = jun
month = jul
month = aug
month = sep
month = oct
month = nov
month = dec
```
**Or numeric**:
```bibtex
month = {1} % January
month = {12} % December
```
**Or full name in braces**:
```bibtex
month = {January}
```
**Standard abbreviations work without quotes** because they're defined in BibTeX.
### Journal Names
**Full name** (not abbreviated):
```bibtex
journal = {Nature}
journal = {Science}
journal = {Cell}
journal = {Proceedings of the National Academy of Sciences}
journal = {Journal of the American Chemical Society}
```
**Bibliography style** will handle abbreviation if needed.
**Avoid manual abbreviation**:
```bibtex
% Don't do this in BibTeX file
journal = {Proc. Natl. Acad. Sci. U.S.A.}
% Do this instead
journal = {Proceedings of the National Academy of Sciences}
```
**Exception**: If style requires abbreviations, use full abbreviated form:
```bibtex
journal = {Proc. Natl. Acad. Sci. U.S.A.} % If required by style
```
### DOI Formatting
**URL format** (preferred):
```bibtex
doi = {10.1038/s41586-021-03819-2}
```
**Not**:
```bibtex
doi = {https://doi.org/10.1038/s41586-021-03819-2} % Don't include URL
doi = {doi:10.1038/s41586-021-03819-2} % Don't include prefix
```
**LaTeX** will format as URL automatically.
**Note**: No period after DOI field!
### URL Formatting
```bibtex
url = {https://www.example.com/article}
```
**Use**:
- When DOI not available
- For web pages
- For supplementary materials
**Don't duplicate**:
```bibtex
% Don't include both if DOI URL is same as url
doi = {10.1038/nature12345}
url = {https://doi.org/10.1038/nature12345} % Redundant!
```
### Special Characters
**Accents and diacritics**:
```bibtex
author = {M{\"u}ller, Hans} % ü
author = {Garc{\'i}a, Jos{\'e}} % í, é
author = {Erd{\H{o}}s, Paul} % ő
author = {Schr{\"o}dinger, Erwin} % ö
```
**Or use UTF-8** (with proper LaTeX setup):
```bibtex
author = {Müller, Hans}
author = {García, José}
```
**Mathematical symbols**:
```bibtex
title = {The $\alpha$-helix Structure}
title = {$\beta$-sheet Prediction}
```
**Chemical formulas**:
```bibtex
title = {H$_2$O Molecular Dynamics}
% Or with chemformula package:
title = {\ce{H2O} Molecular Dynamics}
```
### Field Order
**Recommended order** (for readability):
```bibtex
@article{Key,
author = {},
title = {},
journal = {},
year = {},
volume = {},
number = {},
pages = {},
doi = {},
url = {},
note = {}
}
```
**Rules**:
- Most important fields first
- Consistent across entries
- Use formatter to standardize
## Best Practices
### 1. Consistent Formatting
Use same format throughout:
- Author name format
- Title capitalization
- Journal names
- Citation key style
### 2. Required Fields
Always include:
- All required fields for entry type
- DOI for modern papers (2000+)
- Volume and pages for articles
- Publisher for books
### 3. Protect Capitalization
Use braces for:
- Proper nouns: `{AlphaFold}`
- Acronyms: `{DNA}`, `{CRISPR}`
- Formulas: `{H2O}`
- Names: `{Python}`, `{R}`
### 4. Complete Author Lists
Include all authors when possible:
- All authors if <10
- Use "and others" for 10+
- Don't abbreviate to "et al." manually
### 5. Use Standard Entry Types
Choose correct entry type:
- Journal article → `@article`
- Book → `@book`
- Conference paper → `@inproceedings`
- Preprint → `@misc`
### 6. Validate Syntax
Check for:
- Balanced braces
- Commas after fields
- Unique citation keys
- Valid entry types
### 7. Use Formatters
Use automated tools:
```bash
python scripts/format_bibtex.py references.bib
```
Benefits:
- Consistent formatting
- Catch syntax errors
- Standardize field order
- Fix common issues
## Common Mistakes
### 1. Wrong Author Separator
**Wrong**:
```bibtex
author = {Smith, J.; Doe, J.} % Semicolon
author = {Smith, J., Doe, J.} % Comma
author = {Smith, J. & Doe, J.} % Ampersand
```
**Correct**:
```bibtex
author = {Smith, John and Doe, Jane}
```
### 2. Missing Commas
**Wrong**:
```bibtex
@article{Smith2024,
author = {Smith, John} % Missing comma!
title = {Title}
}
```
**Correct**:
```bibtex
@article{Smith2024,
author = {Smith, John}, % Comma after each field
title = {Title}
}
```
### 3. Unprotected Capitalization
**Wrong**:
```bibtex
title = {Machine Learning with Python}
% "Python" will become "python" in title case
```
**Correct**:
```bibtex
title = {Machine Learning with {Python}}
```
### 4. Single Hyphen in Pages
**Wrong**:
```bibtex
pages = {123-145} % Single hyphen
```
**Correct**:
```bibtex
pages = {123--145} % Double hyphen (en-dash)
```
### 5. Redundant "pp." in Pages
**Wrong**:
```bibtex
pages = {pp. 123--145}
```
**Correct**:
```bibtex
pages = {123--145}
```
### 6. DOI with URL Prefix
**Wrong**:
```bibtex
doi = {https://doi.org/10.1038/nature12345}
doi = {doi:10.1038/nature12345}
```
**Correct**:
```bibtex
doi = {10.1038/nature12345}
```

# Citation Validation Guide
Comprehensive guide to validating citation accuracy, completeness, and formatting in BibTeX files.
## Overview
Citation validation ensures:
- All citations are accurate and complete
- DOIs resolve correctly
- Required fields are present
- No duplicate entries
- Proper formatting and syntax
- Links are accessible
Validation should be performed:
- After extracting metadata
- Before manuscript submission
- After manual edits to BibTeX files
- Periodically for maintained bibliographies
## Validation Categories
### 1. DOI Verification
**Purpose**: Ensure DOIs are valid and resolve correctly.
#### What to Check
**DOI format**:
```
Valid: 10.1038/s41586-021-03819-2
Valid: 10.1126/science.aam9317
Invalid: 10.1038/invalid
Invalid: doi:10.1038/... (should omit "doi:" prefix in BibTeX)
```
**DOI resolution**:
- DOI should resolve via https://doi.org/
- Should redirect to actual article
- Should not return 404 or error
**Metadata consistency**:
- CrossRef metadata should match BibTeX
- Author names should align
- Title should match
- Year should match
#### How to Validate
**Manual check**:
1. Copy DOI from BibTeX
2. Visit https://doi.org/10.1038/nature12345
3. Verify it redirects to correct article
4. Check metadata matches
**Automated check** (recommended):
```bash
python scripts/validate_citations.py references.bib --check-dois
```
**Process**:
1. Extract all DOIs from BibTeX file
2. Query doi.org resolver for each
3. Query CrossRef API for metadata
4. Compare metadata with BibTeX entry
5. Report discrepancies
#### Common Issues
**Broken DOIs**:
- Typos in DOI
- Publisher changed DOI (rare)
- Article retracted
- Solution: Find correct DOI from publisher site
**Mismatched metadata**:
- BibTeX has old/incorrect information
- Solution: Re-extract metadata from CrossRef
**Missing DOIs**:
- Older articles may not have DOIs
- Acceptable for pre-2000 publications
- Add URL or PMID instead
### 2. Required Fields
**Purpose**: Ensure all necessary information is present.
#### Required by Entry Type
**@article**:
```bibtex
author % REQUIRED
title % REQUIRED
journal % REQUIRED
year % REQUIRED
volume % Highly recommended
pages % Highly recommended
doi % Highly recommended for modern papers
```
**@book**:
```bibtex
author OR editor % REQUIRED (at least one)
title % REQUIRED
publisher % REQUIRED
year % REQUIRED
isbn % Recommended
```
**@inproceedings**:
```bibtex
author % REQUIRED
title % REQUIRED
booktitle % REQUIRED (conference/proceedings name)
year % REQUIRED
pages % Recommended
```
**@incollection** (book chapter):
```bibtex
author % REQUIRED
title % REQUIRED (chapter title)
booktitle % REQUIRED (book title)
publisher % REQUIRED
year % REQUIRED
editor % Recommended
pages % Recommended
```
**@phdthesis**:
```bibtex
author % REQUIRED
title % REQUIRED
school % REQUIRED
year % REQUIRED
```
**@misc** (preprints, datasets, etc.):
```bibtex
author % REQUIRED
title % REQUIRED
year % REQUIRED
howpublished % Recommended (bioRxiv, Zenodo, etc.)
doi OR url % At least one required
```
#### Validation Script
```bash
python scripts/validate_citations.py references.bib --check-required-fields
```
**Output**:
```
Error: Entry 'Smith2024' missing required field 'journal'
Error: Entry 'Doe2023' missing required field 'year'
Warning: Entry 'Jones2022' missing recommended field 'volume'
```
### 3. Author Name Formatting
**Purpose**: Ensure consistent, correct author name formatting.
#### Proper Format
**Recommended BibTeX format**:
```bibtex
author = {Last1, First1 and Last2, First2 and Last3, First3}
```
**Examples**:
```bibtex
% Correct
author = {Smith, John}
author = {Smith, John A.}
author = {Smith, John Andrew}
author = {Smith, John and Doe, Jane}
author = {Smith, John and Doe, Jane and Johnson, Mary}
% For many authors
author = {Smith, John and Doe, Jane and others}
% Incorrect
author = {John Smith} % First Last format (not recommended)
author = {Smith, J.; Doe, J.} % Semicolon separator (wrong)
author = {Smith J, Doe J} % Missing commas
```
#### Special Cases
**Suffixes (Jr., III, etc.)**:
```bibtex
author = {King, Jr., Martin Luther}
```
**Multiple surnames (hyphenated)**:
```bibtex
author = {Smith-Jones, Mary}
```
**Van, von, de, etc.**:
```bibtex
author = {van der Waals, Johannes}
author = {de Broglie, Louis}
```
**Organizations as authors**:
```bibtex
author = {{World Health Organization}}
% Double braces treat as single author
```
#### Validation Checks
**Automated validation**:
```bash
python scripts/validate_citations.py references.bib --check-authors
```
**Checks for**:
- Proper separator (and, not &, ; , etc.)
- Comma placement
- Empty author fields
- Malformed names
### 4. Data Consistency
**Purpose**: Ensure all fields contain valid, reasonable values.
#### Year Validation
**Valid years**:
```bibtex
year = {2024} % Current/recent
year = {1953} % Watson & Crick DNA structure (historical)
year = {1665} % Hooke's Micrographia (very old)
```
**Invalid years**:
```bibtex
year = {24} % Two digits (ambiguous)
year = {202} % Typo
year = {2025} % Future (unless accepted/in press)
year = {0} % Obviously wrong
```
**Check**:
- Four digits
- Reasonable range (1600-current+1)
- Not all zeros
#### Volume/Number Validation
```bibtex
volume = {123} % Numeric
volume = {12} % Valid
number = {3} % Valid
number = {S1} % Supplement issue (valid)
```
**Invalid**:
```bibtex
volume = {Vol. 123} % Should be just number
number = {Issue 3} % Should be just number
```
#### Page Range Validation
**Correct format**:
```bibtex
pages = {123--145} % En-dash (two hyphens)
pages = {e0123456} % PLOS-style article ID
pages = {123} % Single page
```
**Incorrect format**:
```bibtex
pages = {123-145} % Single hyphen (use --)
pages = {pp. 123-145} % Remove "pp."
pages = {123–145} % Unicode en-dash (may cause issues)
```
#### URL Validation
**Check**:
- URLs are accessible (return 200 status)
- HTTPS when available
- No obvious typos
- Permanent links (not temporary)
**Valid**:
```bibtex
url = {https://www.nature.com/articles/nature12345}
url = {https://arxiv.org/abs/2103.14030}
```
**Questionable**:
```bibtex
url = {http://...} % HTTP instead of HTTPS
url = {file:///...} % Local file path
url = {bit.ly/...} % URL shortener (not permanent)
```
### 5. Duplicate Detection
**Purpose**: Find and remove duplicate entries.
#### Types of Duplicates
**Exact duplicates** (same DOI):
```bibtex
@article{Smith2024a,
doi = {10.1038/nature12345},
...
}
@article{Smith2024b,
doi = {10.1038/nature12345}, % Same DOI!
...
}
```
**Near duplicates** (similar title/authors):
```bibtex
@article{Smith2024,
title = {Machine Learning for Drug Discovery},
...
}
@article{Smith2024method,
title = {Machine learning for drug discovery}, % Same, different case
...
}
```
**Preprint + Published**:
```bibtex
@misc{Smith2023arxiv,
title = {AlphaFold Results},
howpublished = {arXiv},
...
}
@article{Smith2024,
title = {AlphaFold Results}, % Same paper, now published
journal = {Nature},
...
}
% Keep published version only
```
#### Detection Methods
**By DOI** (most reliable):
- Same DOI = exact duplicate
- Keep one, remove other
**By title similarity**:
- Normalize: lowercase, remove punctuation
- Calculate similarity (e.g., Levenshtein distance)
- Flag if >90% similar
**By author-year-title**:
- Same first author + year + similar title
- Likely duplicate
**Automated detection**:
```bash
python scripts/validate_citations.py references.bib --check-duplicates
```
**Output**:
```
Warning: Possible duplicate entries:
- Smith2024a (DOI: 10.1038/nature12345)
- Smith2024b (DOI: 10.1038/nature12345)
Recommendation: Keep one entry, remove the other.
```
### 6. Format and Syntax
**Purpose**: Ensure valid BibTeX syntax.
#### Common Syntax Errors
**Missing commas**:
```bibtex
@article{Smith2024,
author = {Smith, John} % Missing comma!
title = {Title}
}
% Should be:
author = {Smith, John}, % Comma after each field
```
**Unbalanced braces**:
```bibtex
title = {Title with {Protected} Text % Missing closing brace
% Should be:
title = {Title with {Protected} Text}
```
**Missing closing brace for entry**:
```bibtex
@article{Smith2024,
author = {Smith, John},
title = {Title}
% Missing closing brace!
% Should end with:
}
```
**Invalid characters in keys**:
```bibtex
@article{Smith&Doe2024, % & not allowed in key
...
}
% Use:
@article{SmithDoe2024,
...
}
```
#### BibTeX Syntax Rules
**Entry structure**:
```bibtex
@TYPE{citationkey,
field1 = {value1},
field2 = {value2},
...
fieldN = {valueN}
}
```
**Citation keys**:
- Alphanumeric and some punctuation (-, _, ., :)
- No spaces
- Case-sensitive
- Unique within file
**Field values**:
- Enclosed in {braces} or "quotes"
- Braces preferred for complex text
- Numbers can be unquoted: `year = 2024`
**Special characters**:
- `{` and `}` for grouping
- `\` for LaTeX commands
- Protect capitalization: `{AlphaFold}`
- Accents: `{\"u}`, `{\'e}`, `{\aa}`
#### Validation
```bash
python scripts/validate_citations.py references.bib --check-syntax
```
**Checks**:
- Valid BibTeX structure
- Balanced braces
- Proper commas
- Valid entry types
- Unique citation keys
## Validation Workflow
### Step 1: Basic Validation
Run comprehensive validation:
```bash
python scripts/validate_citations.py references.bib
```
**Checks all**:
- DOI resolution
- Required fields
- Author formatting
- Data consistency
- Duplicates
- Syntax

"doi": "10.1038/nature12345"
}
]
}
```
### Step 3: Fix Issues
**High-priority** (errors):
1. Add missing required fields
2. Fix broken DOIs
3. Remove duplicates
4. Correct syntax errors
**Medium-priority** (warnings):
1. Add recommended fields
2. Improve author formatting
3. Fix page ranges
**Low-priority**:
1. Standardize formatting
2. Add URLs for accessibility
### Step 4: Auto-Fix
Use auto-fix for safe corrections:
```bash
python scripts/validate_citations.py references.bib \
--auto-fix \
--output fixed_references.bib
```
**Auto-fix can**:
- Fix page range format (- to --)
- Remove "pp." from pages
- Standardize author separators
- Fix common syntax errors
- Normalize field order
**Auto-fix cannot**:
- Add missing information
- Find correct DOIs
- Determine which duplicate to keep
- Fix semantic errors
### Step 5: Manual Review
Review auto-fixed file:
```bash
# Check what changed
diff references.bib fixed_references.bib
# Review specific entries that had errors
grep -A 10 "Smith2024" fixed_references.bib
```
### Step 6: Re-Validate
Validate after fixes:
```bash
python scripts/validate_citations.py fixed_references.bib --verbose
```
Should show:
```
✓ All DOIs valid
✓ All required fields present
✓ No duplicates found
✓ Syntax valid
✓ 150/150 entries valid
```
## Validation Checklist
Use this checklist before final submission:
### DOI Validation
- [ ] All DOIs resolve correctly
- [ ] Metadata matches between BibTeX and CrossRef
- [ ] No broken or invalid DOIs
### Completeness
- [ ] All entries have required fields
- [ ] Modern papers (2000+) have DOIs
- [ ] Authors properly formatted
- [ ] Journals/conferences properly named
### Consistency
- [ ] Years are 4-digit numbers
- [ ] Page ranges use -- not -
- [ ] Volume/number are numeric
- [ ] URLs are accessible
### Duplicates
- [ ] No entries with same DOI
- [ ] No near-duplicate titles
- [ ] Preprints updated to published versions
### Formatting
- [ ] Valid BibTeX syntax
- [ ] Balanced braces
- [ ] Proper commas
- [ ] Unique citation keys
### Final Checks
- [ ] Bibliography compiles without errors
- [ ] All citations in text appear in bibliography
- [ ] All bibliography entries cited in text
- [ ] Citation style matches journal requirements
## Best Practices
### 1. Validate Early and Often
```bash
# After extraction
python scripts/extract_metadata.py --doi ... --output refs.bib
python scripts/validate_citations.py refs.bib
# After manual edits
python scripts/validate_citations.py refs.bib
# Before submission
python scripts/validate_citations.py refs.bib --strict
```
### 2. Use Automated Tools
Don't validate manually - use scripts:
- Faster
- More comprehensive
- Catches errors humans miss
- Generates reports
### 3. Keep Backup
```bash
# Before auto-fix
cp references.bib references_backup.bib
# Run auto-fix
python scripts/validate_citations.py references.bib \
--auto-fix \
--output references_fixed.bib
# Review changes
diff references.bib references_fixed.bib
# If satisfied, replace
mv references_fixed.bib references.bib
```
### 4. Fix High-Priority First
**Priority order**:
1. Syntax errors (prevent compilation)
2. Missing required fields (incomplete citations)
3. Broken DOIs (broken links)
4. Duplicates (confusion, wasted space)
5. Missing recommended fields
6. Formatting inconsistencies
### 5. Document Exceptions
For entries that can't be fixed:
```bibtex
@article{Old1950,
author = {Smith, John},
title = {Title},
journal = {Obscure Journal},
year = {1950},
volume = {12},
pages = {34--56},
note = {DOI not available for publications before 2000}
}
```
### 6. Validate Against Journal Requirements
Different journals have different requirements:
- Citation style (numbered, author-year)
- Abbreviations (journal names)
- Maximum reference count
- Format (BibTeX, EndNote, manual)
Check journal author guidelines!
## Common Validation Issues
### Issue 1: Metadata Mismatch
**Problem**: BibTeX says 2023, CrossRef says 2024.
**Cause**:
- Online-first vs print publication
- Correction/update
- Extraction error
**Solution**:
1. Check actual article
2. Use more recent/accurate date
3. Update BibTeX entry
4. Re-validate
### Issue 2: Special Characters
**Problem**: LaTeX compilation fails on special characters.
**Cause**:
- Accented characters (é, ü, ñ)
- Chemical formulas (H₂O)
- Math symbols (α, β, ±)
**Solution**:
```bibtex
% Use LaTeX commands
author = {M{\"u}ller, Hans} % Müller
title = {Study of H\textsubscript{2}O} % H₂O
% Or use UTF-8 with proper LaTeX packages
```
### Issue 3: Incomplete Extraction
**Problem**: Extracted metadata missing fields.
**Cause**:
- Source doesn't provide all metadata
- Extraction error
- Incomplete record
**Solution**:
1. Check original article
2. Manually add missing fields
3. Use alternative source (PubMed vs CrossRef)
### Issue 4: Cannot Find Duplicate
**Problem**: Same paper appears twice, not detected.
**Cause**:
- Different DOIs (should be rare)
- Different titles (abbreviated, typo)
- Different citation keys
**Solution**:
- Manual search for author + year
- Check for similar titles
- Remove manually
## Summary
Validation ensures citation quality:
✓ **Accuracy**: DOIs resolve, metadata correct
✓ **Completeness**: All required fields present
✓ **Consistency**: Proper formatting throughout
✓ **No duplicates**: Each paper cited once
✓ **Valid syntax**: BibTeX compiles without errors
**Always validate** before final submission!
Use automated tools:
```bash
python scripts/validate_citations.py references.bib
```
Follow workflow:
1. Extract metadata
2. Validate
3. Fix errors
4. Re-validate
5. Submit

# Google Scholar Search Guide
Comprehensive guide to searching Google Scholar for academic papers, including advanced search operators, filtering strategies, and metadata extraction.
## Overview
Google Scholar provides the most comprehensive coverage of academic literature across all disciplines:
- **Coverage**: 100+ million scholarly documents
- **Scope**: All academic disciplines
- **Content types**: Journal articles, books, theses, conference papers, preprints, patents, court opinions
- **Citation tracking**: "Cited by" links for forward citation tracking
- **Accessibility**: Free to use, no account required
## Basic Search
### Simple Keyword Search
Search for papers containing specific terms anywhere in the document (title, abstract, full text):
```
CRISPR gene editing
machine learning protein folding
climate change impact agriculture
quantum computing algorithms
```
**Tips**:
- Use specific technical terms
- Include key acronyms and abbreviations
- Start broad, then refine
- Check spelling of technical terms
### Exact Phrase Search
Use quotation marks to search for exact phrases:
```
"deep learning"
"CRISPR-Cas9"
"systematic review"
"randomized controlled trial"
```
**When to use**:
- Technical terms that must appear together
- Proper names
- Specific methodologies
- Exact titles
## Advanced Search Operators
### Author Search
Find papers by specific authors:
```
author:LeCun
author:"Geoffrey Hinton"
author:Church synthetic biology
```
**Variations**:
- Single last name: `author:Smith`
- Full name in quotes: `author:"Jane Smith"`
- Author + topic: `author:Doudna CRISPR`
**Tips**:
- Authors may publish under different name variations
- Try with and without middle initials
- Consider name changes (marriage, etc.)
- Use quotation marks for full names
### Title Search
Search only in article titles:
```
intitle:transformer
intitle:"attention mechanism"
intitle:review climate change
```
**Use cases**:
- Finding papers specifically about a topic
- More precise than full-text search
- Reduces irrelevant results
- Good for finding reviews or methods
### Source (Journal) Search
Search within specific journals or conferences:
```
source:Nature
source:"Nature Communications"
source:NeurIPS
source:"Journal of Machine Learning Research"
```
**Applications**:
- Track publications in top-tier venues
- Find papers in specialized journals
- Identify conference-specific work
- Verify publication venue
### Exclusion Operator
Exclude terms from results:
```
machine learning -survey
CRISPR -patent
climate change -news
deep learning -tutorial -review
```
**Common exclusions**:
- `-survey`: Exclude survey papers
- `-review`: Exclude review articles
- `-patent`: Exclude patents
- `-book`: Exclude books
- `-news`: Exclude news articles
- `-tutorial`: Exclude tutorials
### OR Operator
Search for papers containing any of multiple terms:
```
"machine learning" OR "deep learning"
CRISPR OR "gene editing"
"climate change" OR "global warming"
```
**Best practices**:
- OR must be uppercase
- Combine synonyms
- Include acronyms and spelled-out versions
- Use with exact phrases
### Wildcard Search
Use asterisk (*) as wildcard for unknown words:
```
"machine * learning"
"CRISPR * editing"
"* neural network"
```
**Note**: Limited wildcard support in Google Scholar compared to other databases.
## Advanced Filtering
### Year Range
Filter by publication year:
**Using interface**:
- Click "Since [year]" on left sidebar
- Select custom range
**Using search operators**:
```
# Not directly in search query
# Use interface or URL parameters
```
**In script**:
```bash
python scripts/search_google_scholar.py "quantum computing" \
--year-start 2020 \
--year-end 2024
```
### Sorting Options
**By relevance** (default):
- Google's algorithm determines relevance
- Considers citations, author reputation, publication venue
- Generally good for most searches
**By date**:
- Most recent papers first
- Good for fast-moving fields
- May miss highly cited older papers
- Click "Sort by date" in interface
**By citation count** (via script):
```bash
python scripts/search_google_scholar.py "transformers" \
--sort-by citations \
--limit 50
```
### Language Filtering
**In interface**:
- Settings → Languages
- Select preferred languages
**Default**: English and papers with English abstracts
## Search Strategies
### Finding Seminal Papers
Identify highly influential papers in a field:
1. **Search by topic** with broad terms
2. **Sort by citations** (most cited first)
3. **Look for review articles** for comprehensive overviews
4. **Check publication dates** for foundational vs recent work
**Example**:
```
"generative adversarial networks"
# Sort by citations
# Top results: original GAN paper (Goodfellow et al., 2014), key variants
```
### Finding Recent Work
Stay current with latest research:
1. **Search by topic**
2. **Filter to recent years** (last 1-2 years)
3. **Sort by date** for newest first
4. **Set up alerts** for ongoing tracking
**Example**:
```bash
python scripts/search_google_scholar.py "AlphaFold protein structure" \
--year-start 2023 \
--year-end 2024 \
--limit 50
```
### Finding Review Articles
Get comprehensive overviews of a field:
```
intitle:review "machine learning"
"systematic review" CRISPR
intitle:survey "natural language processing"
```
**Indicators**:
- "review", "survey", "perspective" in title
- Often highly cited
- Published in review journals (Nature Reviews, Trends, etc.)
- Comprehensive reference lists
### Citation Chain Search
**Forward citations** (papers citing a key paper):
1. Find seminal paper
2. Click "Cited by X"
3. See all papers that cite it
4. Identify how field has developed
**Backward citations** (references in a key paper):
1. Find recent review or important paper
2. Check its reference list
3. Identify foundational work
4. Trace development of ideas
**Example workflow**:
```
# Find original transformer paper
"Attention is all you need" author:Vaswani
# Check "Cited by 120,000+"
# See evolution: BERT, GPT, T5, etc.
# Check references in original paper
# Find RNN, LSTM, attention mechanism origins
```
### Comprehensive Literature Search
For thorough coverage (e.g., systematic reviews):
1. **Generate synonym list**:
- Main terms + alternatives
- Acronyms + spelled out
- US vs UK spelling
2. **Use OR operators**:
```
("machine learning" OR "deep learning" OR "neural networks")
```
3. **Combine multiple concepts**:
```
("machine learning" OR "deep learning") ("drug discovery" OR "drug development")
```
4. **Search without date filters** initially:
- Get total landscape
- Filter later if too many results
5. **Export results** for systematic analysis:
```bash
python scripts/search_google_scholar.py \
'"machine learning" OR "deep learning" drug discovery' \
--limit 500 \
--output comprehensive_search.json
```
## Extracting Citation Information
### From Google Scholar Results Page
Each result shows:
- **Title**: Paper title (linked to full text if available)
- **Authors**: Author list (often truncated)
- **Source**: Journal/conference, year, publisher
- **Cited by**: Number of citations + link to citing papers
- **Related articles**: Link to similar papers
- **All versions**: Different versions of the same paper
### Export Options
**Manual export**:
1. Click "Cite" under paper
2. Select BibTeX format
3. Copy citation
**Limitations**:
- One paper at a time
- Manual process
- Time-consuming for many papers
**Automated export** (using script):
```bash
# Search and export to BibTeX
python scripts/search_google_scholar.py "quantum computing" \
--limit 50 \
--format bibtex \
--output quantum_papers.bib
```
### Metadata Available
From Google Scholar you can typically extract:
- Title
- Authors (may be incomplete)
- Year
- Source (journal/conference)
- Citation count
- Link to full text (when available)
- Link to PDF (when available)
**Note**: Metadata quality varies:
- Some fields may be missing
- Author names may be incomplete
- Need to verify with DOI lookup for accuracy
## Rate Limiting and Access
### Rate Limits
Google Scholar has rate limiting to prevent automated scraping:
**Symptoms of rate limiting**:
- CAPTCHA challenges
- Temporary IP blocks
- 429 "Too Many Requests" errors
**Best practices**:
1. **Add delays between requests**: 2-5 seconds minimum
2. **Limit query volume**: Don't search hundreds of queries rapidly
3. **Use scholarly library**: Handles rate limiting automatically
4. **Rotate User-Agents**: Appear as different browsers
5. **Consider proxies**: For large-scale searches (use ethically)
**In our scripts**:
```python
# Automatic rate limiting built in
time.sleep(random.uniform(3, 7)) # Random delay 3-7 seconds
```
### Ethical Considerations
**DO**:
- Respect rate limits
- Use reasonable delays
- Cache results (don't re-query)
- Use official APIs when available
- Attribute data properly
**DON'T**:
- Scrape aggressively
- Use multiple IPs to bypass limits
- Violate terms of service
- Burden servers unnecessarily
- Use data commercially without permission
### Institutional Access
**Benefits of institutional access**:
- Access to full-text PDFs through library subscriptions
- Better download capabilities
- Integration with library systems
- Link resolver to full text
**Setup**:
- Google Scholar → Settings → Library links
- Add your institution
- Links appear in search results
## Tips and Best Practices
### Search Optimization
1. **Start simple, then refine**:
```
# Too specific initially
intitle:"deep learning" intitle:review source:Nature 2023..2024
# Better approach
deep learning review
# Review results
# Add intitle:, source:, year filters as needed
```
2. **Use multiple search strategies**:
- Keyword search
- Author search for known experts
- Citation chaining from key papers
- Source search in top journals
3. **Check spelling and variations**:
- Color vs colour
- Optimization vs optimisation
- Tumor vs tumour
- Try common misspellings if few results
4. **Combine operators strategically**:
```
# Good combination
author:Church intitle:"synthetic biology" 2015..2024
# Find reviews by specific author on topic in recent years
```
### Result Evaluation
1. **Check citation counts**:
- High citations indicate influence
- Recent papers may have low citations but be important
- Citation counts vary by field
2. **Verify publication venue**:
- Peer-reviewed journals vs preprints
- Conference proceedings
- Book chapters
- Technical reports
3. **Check for full text access**:
- [PDF] link on right side
- "All X versions" may have open access version
- Check institutional access
- Try author's website or ResearchGate
4. **Look for review articles**:
- Comprehensive overviews
- Good starting point for new topics
- Extensive reference lists
### Managing Results
1. **Use citation manager integration**:
- Export to BibTeX
- Import to Zotero, Mendeley, EndNote
- Maintain organized library
2. **Set up alerts** for ongoing research:
- Google Scholar → Alerts
- Get emails for new papers matching query
- Track specific authors or topics
3. **Create collections**:
- Save papers to Google Scholar Library
- Organize by project or topic
- Add labels and notes
4. **Export systematically**:
```bash
# Save search results for later analysis
python scripts/search_google_scholar.py "your topic" \
--output topic_papers.json
# Can re-process later without re-searching
python scripts/extract_metadata.py \
--input topic_papers.json \
--output topic_refs.bib
```
## Advanced Techniques
### Boolean Logic Combinations
Combine multiple operators for precise searches:
```
# Highly cited reviews on specific topic by known authors
intitle:review "machine learning" ("drug discovery" OR "drug development")
author:Horvath OR author:Bengio 2020..2024
# Method papers excluding reviews
intitle:method "protein folding" -review -survey
# Papers in top journals only
("Nature" OR "Science" OR "Cell") CRISPR 2022..2024
```
### Finding Open Access Papers
```
# Search with generic terms
machine learning
# Filter by "All versions" which often includes preprints
# Look for green [PDF] links (often open access)
# Check arXiv, bioRxiv versions
```
**In script**:
```bash
python scripts/search_google_scholar.py "topic" \
--open-access-only \
--output open_access_papers.json
```
### Tracking Research Impact
**For a specific paper**:
1. Find the paper
2. Click "Cited by X"
3. Analyze citing papers:
- How is it being used?
- What fields cite it?
- Recent vs older citations?
**For an author**:
1. Search `author:LastName`
2. Check h-index and i10-index
3. View citation history graph
4. Identify most influential papers
**For a topic**:
1. Search topic
2. Sort by citations
3. Identify seminal papers (highly cited, older)
4. Check recent highly-cited papers (emerging important work)
### Finding Preprints and Early Work
```
# arXiv papers
source:arxiv "deep learning"
# bioRxiv papers
source:biorxiv CRISPR
# All preprint servers
("arxiv" OR "biorxiv" OR "medrxiv") your topic
```
**Note**: Preprints are not peer-reviewed. Always check if published version exists.
## Common Issues and Solutions
### Too Many Results
**Problem**: Search returns 100,000+ results, overwhelming.
**Solutions**:
1. Add more specific terms
2. Use `intitle:` to search only titles
3. Filter by recent years
4. Add exclusions (e.g., `-review`)
5. Search within specific journals
### Too Few Results
**Problem**: Search returns 0-10 results, suspiciously few.
**Solutions**:
1. Remove restrictive operators
2. Try synonyms and related terms
3. Check spelling
4. Broaden year range
5. Use OR for alternative terms
### Irrelevant Results
**Problem**: Results don't match intent.
**Solutions**:
1. Use exact phrases with quotes
2. Add more specific context terms
3. Use `intitle:` for title-only search
4. Exclude common irrelevant terms
5. Combine multiple specific terms
### CAPTCHA or Rate Limiting
**Problem**: Google Scholar shows CAPTCHA or blocks access.
**Solutions**:
1. Wait several minutes before continuing
2. Reduce query frequency
3. Use longer delays in scripts (5-10 seconds)
4. Switch to different IP/network
5. Consider using institutional access
### Missing Metadata
**Problem**: Author names, year, or venue missing from results.
**Solutions**:
1. Click through to see full details
2. Check "All versions" for better metadata
3. Look up by DOI if available
4. Extract metadata from CrossRef/PubMed instead
5. Manually verify from paper PDF
### Duplicate Results
**Problem**: Same paper appears multiple times.
**Solutions**:
1. Click "All X versions" to see consolidated view
2. Choose version with best metadata
3. Use deduplication in post-processing:
```bash
python scripts/format_bibtex.py results.bib \
--deduplicate \
--output clean_results.bib
```
## Integration with Scripts
### search_google_scholar.py Usage
**Basic search**:
```bash
python scripts/search_google_scholar.py "machine learning drug discovery"
```
**With year filter**:
```bash
python scripts/search_google_scholar.py "CRISPR" \
--year-start 2020 \
--year-end 2024 \
--limit 100
```
**Sort by citations**:
```bash
python scripts/search_google_scholar.py "transformers" \
--sort-by citations \
--limit 50
```
**Export to BibTeX**:
```bash
python scripts/search_google_scholar.py "quantum computing" \
--format bibtex \
--output quantum.bib
```
**Export to JSON for later processing**:
```bash
python scripts/search_google_scholar.py "topic" \
--format json \
--output results.json
# Later: extract full metadata
python scripts/extract_metadata.py \
--input results.json \
--output references.bib
```
### Batch Searching
For multiple topics:
```bash
# Create file with search queries (queries.txt)
# One query per line
# Search each query
while read query; do
python scripts/search_google_scholar.py "$query" \
--limit 50 \
--output "${query// /_}.json"
sleep 10 # Delay between queries
done < queries.txt
```

doi = {10.5281/zenodo.5123456}
}
```
## Extraction Workflows
### From DOI
**Best practice** - Most reliable source:
```bash
# Single DOI
python scripts/extract_metadata.py --doi 10.1038/s41586-021-03819-2
# Multiple DOIs
python scripts/extract_metadata.py \
--doi 10.1038/nature12345 \
--doi 10.1126/science.abc1234 \
--output refs.bib
```
**Process**:
1. Query CrossRef API with DOI
2. Parse JSON response
3. Extract required fields
4. Determine entry type (@article, @book, etc.)
5. Format as BibTeX
6. Validate completeness
### From PMID
**For biomedical literature**:
```bash
# Single PMID
python scripts/extract_metadata.py --pmid 34265844
# Multiple PMIDs
python scripts/extract_metadata.py \
--pmid 34265844 \
--pmid 28445112 \
--output refs.bib
```
**Process**:
1. Query PubMed EFetch with PMID
2. Parse XML response
3. Extract metadata including MeSH terms
4. Check for DOI in response
5. If DOI exists, optionally query CrossRef for additional metadata
6. Format as BibTeX
### From arXiv ID
**For preprints**:
```bash
python scripts/extract_metadata.py --arxiv 2103.14030
```
**Process**:
1. Query arXiv API with ID
2. Parse Atom XML response
3. Check for published version (DOI in response)
4. If published: Use DOI and CrossRef
5. If not published: Use preprint metadata
6. Format as @misc with preprint note
**Important**: Always check if preprint has been published!
### From URL
**When you only have URL**:
```bash
python scripts/extract_metadata.py \
--url "https://www.nature.com/articles/s41586-021-03819-2"
```
**Process**:
1. Parse URL to extract identifier
2. Identify type (DOI, PMID, arXiv)
3. Extract identifier from URL
4. Query appropriate API
5. Format as BibTeX
**URL patterns**:
```
# DOI URLs
https://doi.org/10.1038/nature12345
https://dx.doi.org/10.1126/science.abc123
https://www.nature.com/articles/s41586-021-03819-2
# PubMed URLs
https://pubmed.ncbi.nlm.nih.gov/34265844/
https://www.ncbi.nlm.nih.gov/pubmed/34265844
# arXiv URLs
https://arxiv.org/abs/2103.14030
https://arxiv.org/pdf/2103.14030.pdf
```
### Batch Processing
**From file with mixed identifiers**:
```bash
# Create file with one identifier per line
# identifiers.txt:
# 10.1038/nature12345
# 34265844
# 2103.14030
# https://doi.org/10.1126/science.abc123
python scripts/extract_metadata.py \
--input identifiers.txt \
--output references.bib
```
**Process**:
- Script auto-detects identifier type
- Queries appropriate API
- Combines all into single BibTeX file
- Handles errors gracefully
## Special Cases and Edge Cases
### Preprints Later Published
**Issue**: Preprint cited, but journal version now available.
**Solution**:
1. Check arXiv metadata for DOI field
2. If DOI present, use published version
3. Update citation to journal article
4. Note preprint version in comments if needed
**Example**:
```bibtex
% Originally: arXiv:2103.14030
% Published as:
@article{Jumper2021,
author = {Jumper, John and Evans, Richard and others},
title = {Highly Accurate Protein Structure Prediction with {AlphaFold}},
journal = {Nature},
year = {2021},
volume = {596},
pages = {583--589},
doi = {10.1038/s41586-021-03819-2}
}
```
### Multiple Authors (et al.)
**Issue**: Many authors (10+).
**BibTeX practice**:
- Include all authors if <10
- Use "and others" for 10+
- Or list all (journals vary)
**Example**:
```bibtex
@article{LargeCollaboration2024,
author = {First, Author and Second, Author and Third, Author and others},
...
}
```
### Author Name Variations
**Issue**: Authors publish under different name formats.
**Standardization**:
```
# Common variations
John Smith
John A. Smith
John Andrew Smith
J. A. Smith
Smith, J.
Smith, J. A.
# BibTeX format (recommended)
author = {Smith, John A.}
```
**Extraction preference**:
1. Use full name if available
2. Include middle initial if available
3. Format: Last, First Middle
### No DOI Available
**Issue**: Older papers or books without DOIs.
**Solutions**:
1. Use PMID if available (biomedical)
2. Use ISBN for books
3. Use URL to stable source
4. Include full publication details
**Example**:
```bibtex
@article{OldPaper1995,
author = {Author, Name},
title = {Title Here},
journal = {Journal Name},
year = {1995},
volume = {123},
pages = {45--67},
url = {https://stable-url-here},
note = {PMID: 12345678}
}
```
### Conference Papers vs Journal Articles
**Issue**: Same work published in both.
**Best practice**:
- Cite journal version if both available
- Journal version is archival
- Conference version for timeliness
**If citing conference**:
```bibtex
@inproceedings{Smith2024conf,
author = {Smith, John},
title = {Title},
booktitle = {Proceedings of NeurIPS 2024},
year = {2024}
}
```
**If citing journal**:
```bibtex
@article{Smith2024journal,
author = {Smith, John},
title = {Title},
journal = {Journal of Machine Learning Research},
year = {2024}
}
```
### Book Chapters vs Edited Collections
**Extract correctly**:
- Chapter: Use `@incollection`
- Whole book: Use `@book`
- Book editor: List in `editor` field
- Chapter author: List in `author` field
### Datasets and Software
**Use @misc** with appropriate fields:
```bibtex
@misc{DatasetName2024,
author = {Author, Name},
title = {Dataset Title},
year = {2024},
howpublished = {Zenodo},
doi = {10.5281/zenodo.123456},
note = {Version 1.2}
}
```
## Validation After Extraction
Always validate extracted metadata:
```bash
python scripts/validate_citations.py extracted_refs.bib
```
**Check**:
- All required fields present
- DOI resolves correctly
- Author names formatted consistently
- Year is reasonable (4 digits)
- Journal/publisher names correct
- Page ranges use -- not -
- Special characters handled properly
## Best Practices
### 1. Prefer DOI When Available
DOIs provide:
- Permanent identifier
- Best metadata source
- Publisher-verified information
- Resolvable link
### 2. Verify Automatically Extracted Metadata
Spot-check:
- Author names match publication
- Title matches (including capitalization)
- Year is correct
- Journal name is complete
### 3. Handle Special Characters
**LaTeX special characters**:
- Protect capitalization: `{AlphaFold}`
- Handle accents: `M{\"u}ller` or use Unicode
- Chemical formulas: `H$_2$O` or `\ce{H2O}`
### 4. Use Consistent Citation Keys
**Convention**: `FirstAuthorYEARkeyword`
```
Smith2024protein
Doe2023machine
Johnson2024cancer
```
### 5. Include DOI for Modern Papers
All papers published after ~2000 should have DOI:
```bibtex
doi = {10.1038/nature12345}
```
### 6. Document Source
For non-standard sources, add note:
```bibtex
note = {Preprint, not peer-reviewed}
note = {Technical report}
note = {Dataset accompanying [citation]}
```
## Summary
Metadata extraction workflow:
1. **Identify**: Determine identifier type (DOI, PMID, arXiv, URL)
2. **Query**: Use appropriate API (CrossRef, PubMed, arXiv)
3. **Extract**: Parse response for required fields
4. **Format**: Create properly formatted BibTeX entry
5. **Validate**: Check completeness and accuracy
6. **Verify**: Spot-check critical citations
**Use scripts** to automate:
- `extract_metadata.py`: Universal extractor
- `doi_to_bibtex.py`: Quick DOI conversion
- `validate_citations.py`: Verify accuracy
**Always validate** extracted metadata before final submission!

# PubMed Search Guide
Comprehensive guide to searching PubMed for biomedical and life sciences literature, including MeSH terms, field tags, advanced search strategies, and E-utilities API usage.
## Overview
PubMed is the premier database for biomedical literature:
- **Coverage**: 35+ million citations
- **Scope**: Biomedical and life sciences
- **Sources**: MEDLINE, life science journals, online books
- **Authority**: Maintained by National Library of Medicine (NLM) / NCBI
- **Access**: Free, no account required
- **Updates**: Daily with new citations
- **Curation**: High-quality metadata, MeSH indexing
## Basic Search
### Simple Keyword Search
PubMed automatically maps terms to MeSH and searches multiple fields:
```
diabetes
CRISPR gene editing
Alzheimer's disease treatment
cancer immunotherapy
```
**Automatic Features**:
- Automatic MeSH mapping
- Plural/singular variants
- Abbreviation expansion
- Spell checking
### Exact Phrase Search
Use quotation marks for exact phrases:
```
"CRISPR-Cas9"
"systematic review"
"randomized controlled trial"
"machine learning"
```
## MeSH (Medical Subject Headings)
### What is MeSH?
MeSH is a controlled vocabulary thesaurus for indexing biomedical literature:
- **Hierarchical structure**: Organized in tree structures
- **Consistent indexing**: Same concept always tagged the same way
- **Comprehensive**: Covers diseases, drugs, anatomy, techniques, etc.
- **Professional curation**: NLM indexers assign MeSH terms
### Finding MeSH Terms
**MeSH Browser**: https://meshb.nlm.nih.gov/search
**Example**:
```
Search: "heart attack"
MeSH term: "Myocardial Infarction"
```
**In PubMed**:
1. Search with keyword
2. Check "MeSH Terms" in left sidebar
3. Select relevant MeSH terms
4. Add to search
### Using MeSH in Searches
**Basic MeSH search**:
```
"Diabetes Mellitus"[MeSH]
"CRISPR-Cas Systems"[MeSH]
"Alzheimer Disease"[MeSH]
"Neoplasms"[MeSH]
```
**MeSH with subheadings**:
```
"Diabetes Mellitus/drug therapy"[MeSH]
"Neoplasms/genetics"[MeSH]
"Heart Failure/prevention and control"[MeSH]
```
**Common subheadings**:
- `/drug therapy`: Drug treatment
- `/diagnosis`: Diagnostic aspects
- `/genetics`: Genetic aspects
- `/epidemiology`: Occurrence and distribution
- `/prevention and control`: Prevention methods
- `/etiology`: Causes
- `/surgery`: Surgical treatment
- `/metabolism`: Metabolic aspects
### MeSH Explosion
By default, MeSH searches include narrower terms (explosion):
```
"Neoplasms"[MeSH]
# Includes: Breast Neoplasms, Lung Neoplasms, etc.
```
**Disable explosion** (exact term only):
```
"Neoplasms"[MeSH:NoExp]
```
### MeSH Major Topic
Search only where MeSH term is a major focus:
```
"Diabetes Mellitus"[MeSH Major Topic]
# Only papers where diabetes is main topic
```
## Field Tags
Field tags specify which part of the record to search.
### Common Field Tags
**Title and Abstract**:
```
cancer[Title] # In title only
treatment[Title/Abstract] # In title or abstract
"machine learning"[Title/Abstract]
```

```
## Boolean Operators
Combine search terms with Boolean logic.
### AND
Both terms must be present (default behavior):
```
diabetes AND treatment
"CRISPR-Cas9" AND "gene editing"
cancer AND immunotherapy AND "clinical trial"[Publication Type]
```
### OR
Either term must be present:
```
"heart attack" OR "myocardial infarction"
diabetes OR "diabetes mellitus"
CRISPR OR Cas9 OR "gene editing"
```
**Use case**: Synonyms and related terms
### NOT
Exclude terms:
```
cancer NOT review
diabetes NOT animal
"machine learning" NOT "deep learning"
```
**Caution**: May exclude relevant papers that mention both terms.
### Combining Operators
Use parentheses for complex logic:
```
(diabetes OR "diabetes mellitus") AND (treatment OR therapy)
("CRISPR" OR "gene editing") AND ("therapeutic" OR "therapy")
AND 2020:2024[Publication Date]
(cancer OR neoplasm) AND (immunotherapy OR "immune checkpoint inhibitor")
AND ("clinical trial"[Publication Type] OR "randomized controlled trial"[Publication Type])

- `pubmed_pmc`: PMC full-text versions
- `pubmed_protein`: Related protein records
### Rate Limiting
**Without API key**:
- 3 requests per second
- Block if exceeded
**With API key**:
- 10 requests per second
- Better for programmatic access
**Best practice**:
```python
import time
time.sleep(0.34) # ~3 requests/second
# or
time.sleep(0.11) # ~10 requests/second with API key
```
### API Key Usage
**Get API key**:
1. Create NCBI account: https://www.ncbi.nlm.nih.gov/account/
2. Settings → API Key Management
3. Create new API key
4. Copy key
**Use in requests**:
```
&api_key=YOUR_API_KEY_HERE
```
**Store securely**:
```bash
# In environment variable
export NCBI_API_KEY="your_key_here"
# In script
import os
api_key = os.getenv('NCBI_API_KEY')
```
## Search Strategies
### Comprehensive Systematic Search
For systematic reviews and meta-analyses:
```
# 1. Identify key concepts
Concept 1: Diabetes
Concept 2: Treatment
Concept 3: Outcomes
# 2. Find MeSH terms and synonyms
Concept 1: "Diabetes Mellitus"[MeSH] OR diabetes OR diabetic
Concept 2: "Drug Therapy"[MeSH] OR treatment OR therapy OR medication
Concept 3: "Treatment Outcome"[MeSH] OR outcome OR efficacy OR effectiveness
# 3. Combine with AND
("Diabetes Mellitus"[MeSH] OR diabetes OR diabetic)
AND ("Drug Therapy"[MeSH] OR treatment OR therapy OR medication)
AND ("Treatment Outcome"[MeSH] OR outcome OR efficacy OR effectiveness)
# 4. Add filters
AND 2015:2024[Publication Date]
AND ("Clinical Trial"[Publication Type] OR "Randomized Controlled Trial"[Publication Type])
AND English[Language]
AND humans[MeSH Terms]
```
### Finding Clinical Trials
```
# Specific disease + clinical trials
"Alzheimer Disease"[MeSH]
AND ("Clinical Trial"[Publication Type]
OR "Randomized Controlled Trial"[Publication Type])
AND 2020:2024[Publication Date]
# Specific drug trials
"Metformin"[MeSH]
AND "Diabetes Mellitus, Type 2"[MeSH]
AND "Randomized Controlled Trial"[Publication Type]
```
### Finding Reviews
```
# Systematic reviews on topic
"CRISPR-Cas Systems"[MeSH]
AND ("Systematic Review"[Publication Type] OR "Meta-Analysis"[Publication Type])
# Reviews in high-impact journals
cancer immunotherapy
AND "Review"[Publication Type]
AND ("Nature"[Journal] OR "Science"[Journal] OR "Cell"[Journal])
```
### Finding Recent Papers
```
# Papers from last year
"machine learning"[Title/Abstract]
AND "drug discovery"[Title/Abstract]
AND 2024[Publication Date]
# Recent papers in specific journal
"CRISPR"[Title/Abstract]
AND "Nature"[Journal]
AND 2023:2024[Publication Date]
```
### Author Tracking
```
# Specific author's recent work
"Doudna JA"[Author] AND 2020:2024[Publication Date]
# Author + topic
"Church GM"[Author] AND "synthetic biology"[Title/Abstract]
```
### High-Quality Evidence
```
# Meta-analyses and systematic reviews
(diabetes OR "diabetes mellitus")
AND (treatment OR therapy)
AND ("Meta-Analysis"[Publication Type] OR "Systematic Review"[Publication Type])
# RCTs only
cancer immunotherapy
AND "Randomized Controlled Trial"[Publication Type]
AND 2020:2024[Publication Date]
```
## Script Integration
### search_pubmed.py Usage
**Basic search**:
```bash
python scripts/search_pubmed.py "diabetes treatment"
```
**With MeSH terms**:
```bash
python scripts/search_pubmed.py \
--query '"Diabetes Mellitus"[MeSH] AND "Drug Therapy"[MeSH]'
```
**Date range filter**:
```bash
python scripts/search_pubmed.py "CRISPR" \
--date-start 2020-01-01 \
--date-end 2024-12-31 \
--limit 200
```
**Publication type filter**:
```bash
python scripts/search_pubmed.py "cancer immunotherapy" \
--publication-types "Clinical Trial,Randomized Controlled Trial" \
--limit 100
```
**Export to BibTeX**:
```bash
python scripts/search_pubmed.py "Alzheimer's disease" \
--limit 100 \
--format bibtex \
--output alzheimers.bib
```
**Complex query from file**:
```bash
# Save complex query in query.txt
cat > query.txt << 'EOF'
("Diabetes Mellitus, Type 2"[MeSH] OR "diabetes"[Title/Abstract])
AND ("Metformin"[MeSH] OR "metformin"[Title/Abstract])
AND "Randomized Controlled Trial"[Publication Type]
AND 2015:2024[Publication Date]
AND English[Language]
EOF
# Run search
python scripts/search_pubmed.py --query-file query.txt --limit 500
```
### Batch Searches
```bash
# Search multiple topics
TOPICS=("diabetes treatment" "cancer immunotherapy" "CRISPR gene editing")
for topic in "${TOPICS[@]}"; do
python scripts/search_pubmed.py "$topic" \
--limit 100 \
--output "${topic// /_}.json"
sleep 1
done
```
### Extract Metadata
```bash
# Search returns PMIDs
python scripts/search_pubmed.py "topic" --output results.json
# Extract full metadata
python scripts/extract_metadata.py \
--input results.json \
--output references.bib
```
## Tips and Best Practices
### Search Construction
1. **Start with MeSH terms**:
- Use MeSH Browser to find correct terms
- More precise than keyword search
- Captures all papers on topic regardless of terminology
2. **Include text word variants**:
```
# Better coverage
("Diabetes Mellitus"[MeSH] OR diabetes OR diabetic)
```
3. **Use field tags appropriately**:
- `[MeSH]` for standardized concepts
- `[Title/Abstract]` for specific terms
- `[Author]` for known authors
- `[Journal]` for specific venues
4. **Build incrementally**:
```
# Step 1: Basic search
diabetes
# Step 2: Add specificity
"Diabetes Mellitus, Type 2"[MeSH]
# Step 3: Add treatment
"Diabetes Mellitus, Type 2"[MeSH] AND "Metformin"[MeSH]
# Step 4: Add study type
"Diabetes Mellitus, Type 2"[MeSH] AND "Metformin"[MeSH]
AND "Clinical Trial"[Publication Type]
# Step 5: Add date range
... AND 2020:2024[Publication Date]
```
### Optimizing Results
1. **Too many results**: Add filters
- Restrict publication type
- Narrow date range
- Add more specific MeSH terms
- Use Major Topic: `[MeSH Major Topic]`
2. **Too few results**: Broaden search
- Remove restrictive filters
- Use OR for synonyms
- Expand date range
- Use MeSH explosion (default)
3. **Irrelevant results**: Refine terms
- Use more specific MeSH terms
- Add exclusions with NOT
- Use Title field instead of all fields
- Add MeSH subheadings
### Quality Control
1. **Document search strategy**:
- Save exact query string
- Record search date
- Note number of results
- Save filters used
2. **Export systematically**:
- Use consistent file naming
- Export to JSON for flexibility
- Convert to BibTeX as needed
- Keep original search results
3. **Validate retrieved citations**:
```bash
python scripts/validate_citations.py pubmed_results.bib
```
### Staying Current
1. **Set up search alerts**:
- PubMed → Save search
- Receive email updates
- Daily, weekly, or monthly
2. **Track specific journals**:
```
"Nature"[Journal] AND CRISPR[Title]
```
3. **Follow key authors**:
```
"Church GM"[Author]
```
## Common Issues and Solutions
### Issue: MeSH Term Not Found
**Solution**:
- Check spelling
- Use MeSH Browser
- Try related terms
- Use text word search as fallback
### Issue: Zero Results
**Solution**:
- Remove filters
- Check query syntax
- Use OR for broader search
- Try synonyms
### Issue: Poor Quality Results
**Solution**:
- Add publication type filters
- Restrict to recent years
- Use MeSH Major Topic
- Filter by journal quality
### Issue: Duplicates from Different Sources
**Solution**:
```bash
python scripts/format_bibtex.py results.bib \
--deduplicate \
--output clean.bib
```
### Issue: API Rate Limiting
**Solution**:
- Get API key (increases limit to 10/sec)
- Add delays in scripts
- Process in batches
- Use off-peak hours

# Clinical Decision Support Skill
Professional clinical decision support documents for medical professionals in pharmaceutical and clinical research settings.
## Quick Start
This skill enables generation of three types of clinical documents:
1. **Individual Patient Treatment Plans** - Personalized protocols for specific patients
2. **Patient Cohort Analysis** - Biomarker-stratified group analyses with outcomes
3. **Treatment Recommendation Reports** - Evidence-based clinical guidelines
All documents are generated as compact, professional LaTeX/PDF files.

(<1%, 1-49%, ≥50%) including ORR, PFS, and OS outcomes
```
### Generate Treatment Recommendations
```
> Create evidence-based treatment recommendations for HER2-positive
metastatic breast cancer with GRADE methodology
```
### Build Clinical Pathway
```
> Generate a clinical decision algorithm for acute chest pain
management with TIMI risk score
```

# Clinical Decision Support Documents
## Description
Generate professional clinical decision support (CDS) documents for pharmaceutical companies, clinical researchers, and medical decision-makers. This skill specializes in analytical, evidence-based documents that inform treatment strategies and drug development:
1. **Patient Cohort Analysis** - Biomarker-stratified group analyses with statistical outcome comparisons
2. **Treatment Recommendation Reports** - Evidence-based clinical guidelines with GRADE grading and decision algorithms
All documents are generated as publication-ready LaTeX/PDF files optimized for pharmaceutical research, regulatory submissions, and clinical guideline development.
**Note:** For individual patient treatment plans at the bedside, use the `treatment-plans` skill instead. This skill focuses on group-level analyses and evidence synthesis for pharmaceutical/research settings.
## Capabilities
### Document Types
**Patient Cohort Analysis**
- Biomarker-based patient stratification (molecular subtypes, gene expression, IHC)
- Molecular subtype classification (e.g., GBM mesenchymal-immune-active vs proneural, breast cancer subtypes)
- Outcome metrics with statistical analysis (OS, PFS, ORR, DOR, DCR)
- Statistical comparisons between subgroups (hazard ratios, p-values, 95% CI)
- Survival analysis with Kaplan-Meier curves and log-rank tests
- Efficacy tables and waterfall plots
- Comparative effectiveness analyses
- Pharmaceutical cohort reporting (trial subgroups, real-world evidence)
**Treatment Recommendation Reports**
- Evidence-based treatment guidelines for specific disease states
- Strength of recommendation grading (GRADE system: 1A, 1B, 2A, 2B, 2C)
- Quality of evidence assessment (high, moderate, low, very low)
- Treatment algorithm flowcharts with TikZ diagrams
- Line-of-therapy sequencing based on biomarkers
- Decision pathways with clinical and molecular criteria
- Pharmaceutical strategy documents
- Clinical guideline development for medical societies
### Clinical Features
- **Biomarker Integration**: Genomic alterations (mutations, CNV, fusions), gene expression signatures, IHC markers, PD-L1 scoring
- **Statistical Analysis**: Hazard ratios, p-values, confidence intervals, survival curves, Cox regression, log-rank tests
- **Evidence Grading**: GRADE system (1A/1B/2A/2B/2C), Oxford CEBM levels, quality of evidence assessment
- **Clinical Terminology**: SNOMED-CT, LOINC, proper medical nomenclature, trial nomenclature
- **Regulatory Compliance**: HIPAA de-identification, confidentiality headers, ICH-GCP alignment
- **Professional Formatting**: Compact 0.5in margins, color-coded recommendations, publication-ready, suitable for regulatory submissions
## Pharmaceutical and Research Use Cases

- **Compare outcomes** between patient subgroups with statistical analysis (survival, response rates, hazard ratios)
- **Produce pharmaceutical research documents** for drug development, clinical trials, or regulatory submissions
- **Develop clinical practice guidelines** with GRADE evidence grading and decision algorithms
- **Document biomarker-guided therapy selection** at the population level (not individual patients)
- **Synthesize evidence** from multiple trials or real-world data sources
- **Create clinical decision algorithms** with flowcharts for treatment sequencing
**Do NOT use this skill for:**
- Individual patient treatment plans (use `treatment-plans` skill)
- Bedside clinical care documentation (use `treatment-plans` skill)
- Simple patient-specific treatment protocols (use `treatment-plans` skill)
## Visual Enhancement with Scientific Schematics
**When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.**
If your document does not already contain schematics or diagrams:
- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams
- Simply describe your desired diagram in natural language
- Nano Banana Pro will automatically generate, review, and refine the schematic
**For new documents:** Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.
**How to generate schematics:**
```bash
python scripts/generate_schematic.py "your diagram description" -o figures/output.png
```
The AI will automatically:
- Create publication-quality images with proper formatting
- Review and refine through multiple iterations
- Ensure accessibility (colorblind-friendly, high contrast)
- Save outputs in the figures/ directory
**When to add schematics:**
- Clinical decision algorithm flowcharts
- Treatment pathway diagrams
- Biomarker stratification trees
- Patient cohort flow diagrams (CONSORT-style)
- Survival curve visualizations
- Molecular mechanism diagrams
- Any complex concept that benefits from visualization
For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.

## Best Practices
### For Cohort Analyses
1. **Patient Selection Transparency**: Clearly document inclusion/exclusion criteria, patient flow, and reasons for exclusions
2. **Biomarker Clarity**: Specify assay methods, platforms (e.g., FoundationOne, Caris), cut-points, and validation status
3. **Statistical Rigor**:
- Report hazard ratios with 95% confidence intervals, not just p-values
- Include median follow-up time for survival analyses
- Specify statistical tests used (log-rank, Cox regression, Fisher's exact)
- Account for multiple comparisons when appropriate
4. **Outcome Definitions**: Use standard criteria:
- Response: RECIST 1.1, iRECIST for immunotherapy
- Adverse events: CTCAE version 5.0
- Performance status: ECOG or Karnofsky
5. **Survival Data Presentation**:
- Median OS/PFS with 95% CI
- Landmark survival rates (6-month, 12-month, 24-month)
- Number at risk tables below Kaplan-Meier curves
- Censoring clearly indicated
6. **Subgroup Analyses**: Pre-specify subgroups; clearly label exploratory vs pre-planned analyses
7. **Data Completeness**: Report missing data and how it was handled
### For Treatment Recommendation Reports
1. **Evidence Grading Transparency**:
- Use GRADE system consistently (1A, 1B, 2A, 2B, 2C)
- Document rationale for each grade
- Clearly state quality of evidence (high, moderate, low, very low)
2. **Comprehensive Evidence Review**:
- Include phase 3 randomized trials as primary evidence
- Supplement with phase 2 data for emerging therapies
- Note real-world evidence and meta-analyses
- Cite trial names (e.g., KEYNOTE-189, CheckMate-227)
3. **Biomarker-Guided Recommendations**:
- Link specific biomarkers to therapy recommendations
- Specify testing methods and validated assays
- Include FDA/EMA approval status for companion diagnostics
4. **Clinical Actionability**: Every recommendation should have clear implementation guidance
5. **Decision Algorithm Clarity**: TikZ flowcharts should be unambiguous with clear yes/no decision points
6. **Special Populations**: Address elderly, renal/hepatic impairment, pregnancy, drug interactions
7. **Monitoring Guidance**: Specify safety labs, imaging, and frequency
8. **Update Frequency**: Date recommendations and plan for periodic updates
### General Best Practices
1. **First Page Executive Summary (MANDATORY)**:
- ALWAYS create a complete executive summary on page 1 that spans the entire first page
- Use 3-5 colored tcolorbox elements to highlight key findings
- No table of contents or detailed sections on page 1
- Use `\thispagestyle{empty}` and end with `\newpage`
- This is the single most important page - it should be scannable in 60 seconds
2. **De-identification**: Remove all 18 HIPAA identifiers before document generation (Safe Harbor method)
3. **Regulatory Compliance**: Include confidentiality notices for proprietary pharmaceutical data
4. **Publication-Ready Formatting**: Use 0.5in margins, professional fonts, color-coded sections
5. **Reproducibility**: Document all statistical methods to enable replication
6. **Conflict of Interest**: Disclose pharmaceutical funding or relationships when applicable
7. **Visual Hierarchy**: Use colored boxes consistently (blue=data, green=biomarkers, yellow/orange=recommendations, red=warnings)

\begin{tcolorbox}[enhanced,colback=stronggreen!10,colframe=tier1green,
title=\textbf{PERSONALIZED TREATMENT PLAN},fonttitle=\bfseries,coltitle=black]
{\small
Based on the genomic profile, the following treatment approach is recommended:
\textbf{Primary Recommendation (GRADE 1A)}:
\begin{itemize}
\item \textbf{[Drug targeting identified alteration]}
\item Dosing: [Specific dose and schedule]
\item Evidence: [Supporting data]
\item Expected outcomes: ORR XX\%, median PFS XX months
\end{itemize}
\textbf{If Primary Recommendation Contraindicated}:
\begin{itemize}
\item Alternative 1: [Second-line biomarker-directed option]
\item Alternative 2: [Standard therapy if targeted therapy ineligible]
\end{itemize}
\textbf{At Progression}:
\begin{itemize}
\item Repeat molecular profiling (liquid biopsy or tissue) for resistance mechanisms
\item Expected resistance alterations: [e.g., EGFR T790M, MET amplification]
\item Sequential targeted therapy if secondary actionable alteration identified
\end{itemize}
\textbf{Clinical Trial Matching}:
\begin{itemize}
\item [List relevant trials based on identified alterations]
\item ClinicalTrials.gov search terms: [Suggested keywords]
\end{itemize}
}
\end{tcolorbox}
\section{Clinical Trial Matching}
\begin{table}[H]
\centering
\small
\begin{tabular}{llll}
\toprule
\textbf{Trial} & \textbf{Intervention} & \textbf{Biomarker} & \textbf{Phase} \\
\midrule
[NCT Number] & [Drug/regimen] & [Matching biomarker] & Phase [1/2/3] \\
[NCT Number] & [Drug/regimen] & [Matching biomarker] & Phase [1/2/3] \\
\bottomrule
\end{tabular}
\caption{Potential clinical trials based on molecular profile (as of [date])}
\end{table}
\textit{Note: Trial availability changes frequently. Search ClinicalTrials.gov for current options.}
\section{Methodology}
\subsection{Assay Information}
\textbf{Test Name}: [FoundationOne CDx / Custom NGS Panel / Other]\\
\textbf{Methodology}: Next-generation sequencing (NGS)\\
\textbf{Genes Analyzed}: [Number] genes for SNVs, indels, CNVs, and rearrangements\\
\textbf{Coverage Depth}: [XXX]x median coverage\\
\textbf{Limit of Detection}: [X\%] variant allele frequency
\textbf{Specimen Details}:
\begin{itemize}
\item Specimen type: [FFPE tissue block / Blood (ctDNA)]
\item Tumor content: [XX\%] (minimum 20\% required for optimal sensitivity)
\item DNA quality: [Adequate / Suboptimal]
\item DNA quantity: [XX ng] (minimum [Y ng] required)
\end{itemize}
\subsection{Interpretation}
\textbf{Variant Classification}:
\begin{itemize}
\item Pathogenic: Disease-causing, clinically significant
\item Likely Pathogenic: Probably disease-causing based on available evidence
\item VUS: Uncertain significance, insufficient evidence for classification
\item Likely Benign: Probably not disease-causing
\item Benign: Not disease-causing
\end{itemize}
\textbf{Databases Referenced}:
\begin{itemize}
\item OncoKB (Memorial Sloan Kettering)
\item CIViC (Clinical Interpretations of Variants in Cancer)
\item ClinVar (NCBI)
\item COSMIC (Catalogue of Somatic Mutations in Cancer)
\item [Others - PMKB, CGI, etc.]
\end{itemize}
\section{Limitations}
\begin{itemize}
\item This test analyzes [somatic/germline] alterations in tumor tissue. [If somatic: Results not informative for inherited cancer risk]
\item Negative result does not exclude presence of alterations in genes not covered by this panel
\item Low VAF alterations (<5\%) may not be detected due to assay sensitivity limits
\item Copy number analysis limited for small amplifications or deletions
\item Structural variants detection depends on breakpoint location within sequenced regions
\item TMB and MSI calculations are estimate-based; consider orthogonal testing if borderline
\end{itemize}
\section{Recommendations for Referring Clinician}
\begin{enumerate}
\item \textbf{[Action 1]}: [e.g., Initiate targeted therapy with drug X based on detected alteration]
\item \textbf{[Action 2]}: [e.g., Consider clinical trial enrollment for Tier 2 alteration]
\item \textbf{[Action 3]}: [e.g., Repeat molecular profiling at progression to identify resistance mechanisms]
\item \textbf{[Action 4]}: [e.g., If MSI-H detected and patient <50 years, refer for genetic counseling for Lynch syndrome]
\item \textbf{[Action 5]}: [e.g., Share report with molecular tumor board for complex decision-making]
\end{enumerate}

\section{Statistical Analysis}
\subsection{Methods}
\textbf{Study Design}: [Retrospective cohort analysis / Prospective cohort / Post-hoc analysis of clinical trial]
\textbf{Statistical Tests}:
\begin{itemize}
\item Continuous variables: [t-test / Mann-Whitney U test], reported as [mean $\pm$ SD / median [IQR]]
\item Categorical variables: Chi-square test or Fisher's exact test (if expected count <5)
\item Survival analysis: Kaplan-Meier method, log-rank test, Cox proportional hazards regression
\item Significance level: Two-sided p<0.05 considered statistically significant
\item Software: [R version X.X.X, survival package / SAS / Stata / Python lifelines]
\end{itemize}
\subsection{Multivariable Analysis}
Cox regression model adjusting for baseline prognostic factors:
\begin{table}[H]
\centering
\small
\begin{tabular}{lccc}
\toprule
\textbf{Variable} & \textbf{Hazard Ratio} & \textbf{95\% CI} & \textbf{p-value} \\

Biomarker+ (vs Biomarker-) & X.XX & X.XX-X.XX & X.XXX \\
Age (per 10 years) & X.XX & X.XX-X.XX & X.XXX \\
ECOG PS 2 (vs 0-1) & X.XX & X.XX-X.XX & X.XXX \\
Stage IV (vs III) & X.XX & X.XX-X.XX & X.XXX \\
[Additional variable] & X.XX & X.XX-X.XX & X.XXX \\
\bottomrule
\end{tabular}
\caption{Multivariable Cox regression for progression-free survival}

# Example: GBM Molecular Subtype Cohort Analysis
## Clinical Context
This example demonstrates a patient cohort analysis stratified by molecular biomarkers, similar to the GBM Mesenchymal-Immune-Active cluster analysis provided as reference.
## Cohort Overview
**Disease**: Glioblastoma (GBM), IDH-wild-type
**Study Population**: n=60 patients with newly diagnosed GBM treated with standard Stupp protocol (temozolomide + radiation → adjuvant temozolomide)
**Molecular Classification**: Verhaak 2010 subtypes with immune signature refinement
- **Group A**: Mesenchymal-Immune-Active subtype (n=18, 30%)
- **Group B**: Other molecular subtypes (Proneural, Classical, Neural) (n=42, 70%)
**Study Period**: January 2019 - December 2022
**Data Source**: Single academic medical center, retrospective cohort analysis
## Biomarker Classification
### Mesenchymal-Immune-Active Subtype Characteristics
**Molecular Features**:
- NF1 alterations (mutations or deletions): 72% (13/18)
- High YKL-40 (CHI3L1) expression: 100% (18/18, median z-score +2.8)
- Immune gene signature: Elevated (median ESTIMATE immune score +1250)
- CD163+ macrophage infiltration: High density (median 195 cells/mm², range 120-340)
- MES (mesenchymal) signature score: >0.5 (all patients)
**Clinical Characteristics**:
- Median age: 64 years (range 42-76)
- Male: 61% (11/18)
- Tumor location: Temporal lobe predominant (55%)
- Multifocal disease: 33% (6/18) - higher than overall cohort
### Comparison Groups (Other Subtypes)
**Molecular Features**:
- Proneural: n=15 (25%) - PDGFRA amplification, younger age
- Classical: n=18 (30%) - EGFR amplification, chromosome 7+/10-
- Neural: n=9 (15%) - neuronal markers, may include normal tissue
## Treatment Outcomes
### Response Assessment (RANO Criteria)
**Objective Response Rate** (after chemoradiation, ~3 months):
- Mesenchymal-Immune-Active: 6/18 (33%) - CR 0, PR 6
- Other subtypes: 18/42 (43%) - CR 1, PR 17
- p = 0.48 (Fisher's exact)
**Interpretation**: No significant difference in initial response rates
### Survival Outcomes
**Progression-Free Survival (PFS)**:
- Mesenchymal-Immune-Active: Median 7.2 months (95% CI 5.8-9.1)
- Other subtypes: Median 9.5 months (95% CI 8.1-11.3)
- Hazard Ratio: 1.58 (95% CI 0.89-2.81), p = 0.12
- 6-month PFS rate: 61% vs 74%
**Overall Survival (OS)**:
- Mesenchymal-Immune-Active: Median 12.8 months (95% CI 10.2-15.4)
- Other subtypes: Median 16.3 months (95% CI 14.7-18.9)
- Hazard Ratio: 1.72 (95% CI 0.95-3.11), p = 0.073
- 12-month OS rate: 55% vs 68%
- 24-month OS rate: 17% vs 31%
**Interpretation**: Trend toward worse survival in mesenchymal-immune-active subtype, not reaching statistical significance in this cohort size
### Response to Bevacizumab at Recurrence
**Subset Analysis** (patients receiving bevacizumab at first recurrence, n=35):
- Mesenchymal-Immune-Active: n=12
- ORR: 58% (7/12)
- Median PFS2 (from bevacizumab start): 6.8 months
- Other subtypes: n=23
- ORR: 35% (8/23)
- Median PFS2: 4.2 months
- p = 0.19 (Fisher's exact for ORR)
- HR for PFS2: 0.62 (95% CI 0.29-1.32), p = 0.21
**Interpretation**: Exploratory finding suggesting enhanced benefit from bevacizumab in mesenchymal-immune-active subtype (not statistically significant with small sample)
## Safety Profile
**Treatment-Related Adverse Events** (Temozolomide):
No significant differences in toxicity between molecular subtypes:
- Lymphopenia (any grade): 89% vs 86%, p = 0.77
- Thrombocytopenia (grade 3-4): 22% vs 19%, p = 0.79
- Fatigue (any grade): 94% vs 90%, p = 0.60
- Treatment discontinuation: 17% vs 14%, p = 0.77
## Clinical Implications
### Treatment Recommendations
**For Mesenchymal-Immune-Active GBM**:
1. **First-Line**: Standard Stupp protocol (no change based on subtype)
- Evidence: No proven benefit for alternative first-line strategies
- GRADE: 1A (strong recommendation, high-quality evidence)
2. **At Recurrence - Consider Bevacizumab Earlier**:
- Rationale: Exploratory data suggesting enhanced anti-angiogenic response
- Evidence: Mesenchymal GBM has high VEGF expression, angiogenic phenotype
- GRADE: 2C (conditional recommendation, low-quality evidence from subset)
3. **Clinical Trial Enrollment - Immunotherapy Combinations**:
- Rationale: High immune cell infiltration may predict immunotherapy benefit
- Targets: PD-1/PD-L1 blockade ± anti-CTLA-4 or anti-angiogenic agents
- Evidence: Ongoing trials (CheckMate-498, CheckMate-548 showed negative results, but did not select for immune-active)
- GRADE: R (research recommendation)
**For Other GBM Subtypes**:
- Standard treatment per NCCN guidelines
- Consider tumor treating fields (Optune) after radiation completion
- Clinical trials based on specific molecular features (EGFR amplification → EGFR inhibitor trials)
### Prognostic Information
**Counseling Patients**:
- Mesenchymal-immune-active subtype associated with trend toward shorter survival (12.8 vs 16.3 months)
- Not definitive due to small sample size and confidence intervals overlapping
- Prospective validation needed
- Should not alter standard first-line treatment
## Study Limitations
1. **Small Sample Size**: n=18 in mesenchymal-immune-active group limits statistical power
2. **Retrospective Design**: Potential selection bias, unmeasured confounders
3. **Single Institution**: May not generalize to other populations
4. **Heterogeneous Recurrence Treatment**: Not all patients received bevacizumab; treatment selection bias
5. **Molecular Classification**: Based on bulk tumor RNA-seq; intratumoral heterogeneity not captured
6. **No Central Pathology Review**: Molecular classification performed locally
## Future Directions
1. **Prospective Validation**: Confirm survival differences in independent cohort (n>100 per group for adequate power)
2. **Biomarker Testing**: Develop clinically feasible assay for mesenchymal-immune subtype identification
3. **Clinical Trial Design**: Immunotherapy combinations targeting mesenchymal-immune-active GBM specifically
4. **Mechanistic Studies**: Investigate why mesenchymal-immune GBM may respond better to bevacizumab
5. **Longitudinal Analysis**: Track molecular subtype evolution over treatment course
## Data Presentation Example

```
## Key Takeaways
1. **Molecular heterogeneity exists** in GBM with distinct subtypes
2. **Mesenchymal-immune-active subtype** characterized by NF1 alterations, immune infiltration
3. **Trend toward worse prognosis** but not statistically significant (power limitations)
4. **Potential bevacizumab benefit** hypothesis-generating, requires prospective validation
5. **Immunotherapy target**: High immune infiltration rational for checkpoint inhibitor trials
6. **Clinical implementation pending**: Need prospective validation before routine subtyping

# Recommendation Strength Guide
## GRADE Framework for Clinical Recommendations
### Components of a Recommendation
Every clinical recommendation should address:
1. **Population**: Who should receive the intervention?
2. **Intervention**: What specific treatment/action?
3. **Comparator**: Compared to what alternative?
4. **Outcome**: What are the expected results?
5. **Strength**: How strong is the recommendation?
6. **Quality of Evidence**: How confident are we in the evidence?
### Recommendation Strength (Grade 1 vs Grade 2)
#### Strong Recommendation (Grade 1)
**When to Use**:
- Desirable effects clearly outweigh undesirable effects (or vice versa)
- High or moderate quality evidence
- Values and preferences: Little variability expected
- Resource implications: Cost-effective or cost considerations minor
**Wording**: "We recommend..." or "Clinicians should..."
**Implications**:
- Most patients should receive the recommended intervention
- Adherence to recommendation could be a quality indicator
- Policy-makers can adapt as performance measure
**Examples**:
```
STRONG RECOMMENDATION FOR (Grade 1):
"We recommend osimertinib 80 mg daily as first-line therapy for adults with
advanced NSCLC harboring EGFR exon 19 deletion or L858R mutation (Strong
recommendation, High-quality evidence - GRADE 1A)."
Rationale:
- Large PFS benefit: 18.9 vs 10.2 months (HR 0.46, p<0.001)
- OS benefit: 38.6 vs 31.8 months (HR 0.80, p=0.046)
- Better tolerability: Lower grade 3-4 AEs
- Evidence: High-quality (large RCT, low risk of bias)
- Benefits clearly outweigh harms
```
```
STRONG RECOMMENDATION AGAINST (Grade 1):
"We recommend against using bevacizumab in the first-line treatment of newly
diagnosed glioblastoma to improve overall survival (Strong recommendation against,
High-quality evidence - GRADE 1A)."
Rationale:
- No OS benefit: HR 0.88 (0.76-1.02), p=0.10 (AVAglio trial)
- Toxicity: Increased grade ≥3 AEs (66% vs 52%)
- Evidence: High-quality (two large phase 3 RCTs)
- Harms outweigh lack of survival benefit
```
#### Conditional/Weak Recommendation (Grade 2)
**When to Use**:
- Desirable and undesirable effects closely balanced
- Low or very low quality evidence
- Values and preferences: Substantial variability
- Resource implications: High cost or limited access
**Wording**: "We suggest..." or "Clinicians might..."
**Implications**:
- Different choices will be appropriate for different patients
- Shared decision-making essential
- Policy-making requires substantial debate and stakeholder involvement
**Examples**:
```
CONDITIONAL RECOMMENDATION FOR (Grade 2):
"We suggest considering maintenance pemetrexed after first-line platinum-pemetrexed
chemotherapy for advanced non-squamous NSCLC in patients without disease progression
(Conditional recommendation, Moderate-quality evidence - GRADE 2B)."
Rationale:
- Modest PFS benefit: 4.0 vs 2.0 months (HR 0.62)
- No OS benefit: 13.9 vs 11.0 months (HR 0.79, p=0.23)
- Toxicity: Continued chemotherapy burden
- Quality of life: Trade-off between symptom control and treatment side effects
- Patient values: Some prioritize time off treatment, others prioritize disease control
- Shared decision-making essential
```
```
CONDITIONAL RECOMMENDATION - EITHER OPTION ACCEPTABLE (Grade 2):
"We suggest either pembrolizumab monotherapy OR pembrolizumab plus platinum-doublet
chemotherapy as first-line treatment for PD-L1 ≥50% NSCLC, based on patient
preferences and clinical factors (Conditional recommendation, High-quality evidence -
GRADE 2A)."
Rationale:
- Both regimens NCCN Category 1 preferred
- Monotherapy: Less toxicity, oral vs IV, better quality of life
- Combination: Higher ORR (48% vs 39%), numerically longer PFS
- OS: Similar between strategies
- Patient values: Varies widely (tolerability vs response rate priority)
```
### Evidence Quality (⊕⊕⊕⊕ to ⊕○○○)
#### High Quality (⊕⊕⊕⊕)
- Further research very unlikely to change confidence in effect estimate
- Consistent results from well-designed RCTs
- No serious limitations
- Direct evidence (target population, intervention, outcomes)
- Precise estimate (narrow CI)
**Example**: FLAURA trial for osimertinib in EGFR+ NSCLC - Large RCT, consistent results, low risk of bias, direct outcomes
#### Moderate Quality (⊕⊕⊕○)
- Further research likely to impact confidence and may change estimate
- RCTs with some limitations OR very strong evidence from observational studies
- Some inconsistency, indirectness, imprecision, or publication bias
**Example**: Single RCT with some limitations, or multiple RCTs with moderate heterogeneity
#### Low Quality (⊕⊕○○)
- Further research very likely to have important impact on confidence in estimate
- Observational studies OR RCTs with serious limitations
- Serious issues with consistency, directness, precision, or bias
**Example**: Well-conducted cohort study, or RCT with high attrition and unclear allocation concealment
#### Very Low Quality (⊕○○○)
- Estimate of effect very uncertain
- Case series, expert opinion, mechanistic reasoning
- Very serious limitations
**Example**: Retrospective case series, expert consensus without systematic review
## Combining Strength and Quality
### All Nine Possible Combinations
| Evidence Quality | Strong For (↑↑) | Weak For (↑) | Strong Against (↓↓) | Weak Against (↓) |
|-----------------|----------------|--------------|---------------------|------------------|
| **High (⊕⊕⊕⊕)** | Grade 1A | Grade 2A | Grade 1A (against) | Grade 2A (against) |
| **Moderate (⊕⊕⊕○)** | Grade 1B | Grade 2B | Grade 1B (against) | Grade 2B (against) |
| **Low (⊕⊕○○)** | Grade 1C* | Grade 2C | Grade 1C (against)* | Grade 2C (against) |
| **Very Low (⊕○○○)** | Grade 1D* | Grade 2D | Grade 1D (against)* | Grade 2D (against) |
*Rare: Strong recommendations usually require at least moderate-quality evidence
### Unusual Combinations (When They Occur)
**Strong Recommendation with Low Quality Evidence (Grade 1C)**
Rare, but can occur when:
- Large magnitude of effect from observational data (RR >5 or <0.2)
- Low quality evidence, but clear benefit-harm balance
- Example: Anticoagulation for atrial fibrillation (before RCTs, strong observational data)
**Weak Recommendation with High Quality Evidence (Grade 2A)**
Occurs when:
- Benefits and harms closely balanced
- Patient values highly variable
- Example: Aspirin for primary prevention in low-risk individuals (benefits small, bleeding risk present, patient values vary)
## Wording Templates
### Strong Recommendations
**FOR (↑↑)**:
- "We recommend [intervention] for [population]."
- "Clinicians should [action]."
- "[Intervention] is recommended."
**AGAINST (↓↓)**:
- "We recommend against [intervention] for [population]."
- "Clinicians should not [action]."
- "[Intervention] is not recommended."
### Conditional/Weak Recommendations
**FOR (↑)**:
- "We suggest [intervention] for [population]."
- "Clinicians might consider [action]."
- "[Intervention] may be considered for selected patients."
**AGAINST (↓)**:
- "We suggest not using [intervention] for [population]."
- "Clinicians might avoid [action]."
- "[Intervention] is generally not recommended."
**EITHER ACCEPTABLE**:
- "We suggest either [option A] or [option B] based on patient preferences."
- "Either approach is reasonable."
## Color Coding for Visual Documents
**Strong Recommendations (Green Background)**:
- RGB(0, 153, 76) or #009954
- Clear visual priority
- Use for Grade 1A, 1B
**Conditional Recommendations (Yellow Background)**:
- RGB(255, 193, 7) or #FFC107
- Indicates discussion needed
- Use for Grade 2A, 2B, 2C
**Research/Investigational (Blue Background)**:
- RGB(33, 150, 243) or #2196F3
- Clinical trial consideration
- Insufficient evidence for standard care
**Not Recommended (Red Border/Background)**:
- RGB(220, 20, 60) or #DC143C
- Strong recommendation against
- Evidence of harm or no benefit
## Common Scenarios
### Scenario 1: Strong Evidence, Clear Benefit-Harm Balance
**Example**: Pembrolizumab for PD-L1 ≥50% NSCLC
- Evidence: Large phase 3 RCT (KEYNOTE-024), n=305, well-designed
- Results: PFS HR 0.50 (0.37-0.68), OS HR 0.60 (0.41-0.89)
- Toxicity: Lower grade 3-5 AEs than chemotherapy (27% vs 53%)
- Patient values: Most prioritize efficacy and tolerability
**Recommendation**: STRONG FOR (Grade 1A)
### Scenario 2: Moderate Evidence, Balanced Trade-Offs
**Example**: Adjuvant immunotherapy for resected melanoma
- Evidence: RCT showing relapse-free survival benefit, OS data immature
- Results: Recurrence risk reduced but ongoing toxicity
- Toxicity: Immune-related AEs requiring steroids (some severe)
- Cost: High annual cost for 12 months treatment
- Patient values: Variable (some prioritize recurrence prevention, others avoid toxicity)
**Recommendation**: CONDITIONAL FOR (Grade 2B)
### Scenario 3: Low Evidence, but Severe Consequence
**Example**: Anticoagulation for prosthetic heart valve
- Evidence: No RCTs (would be unethical), observational data and mechanistic reasoning
- Consequence: Very high thromboembolic risk without anticoagulation
- Benefit-harm: Clear despite low quality evidence
**Recommendation**: STRONG FOR (Grade 1C)
### Scenario 4: High Evidence, but Patient Preferences Vary
**Example**: Breast reconstruction after mastectomy
- Evidence: High-quality data on outcomes and satisfaction
- Trade-offs: Cosmetic benefit vs additional surgery, recovery time
- Values: Highly personal decision, wide preference variability
**Recommendation**: CONDITIONAL (Grade 2A) - discuss options, patient decides

# Biomarker Classification and Interpretation Guide
## Overview
Biomarkers are measurable indicators of biological state or condition. In clinical decision support, biomarkers guide diagnosis, prognosis, treatment selection, and monitoring. This guide covers genomic, proteomic, and molecular biomarkers with emphasis on clinical actionability.
## Biomarker Categories
### Prognostic Biomarkers
**Definition**: Predict clinical outcome (survival, recurrence) regardless of treatment received
**Examples by Disease**
**Cancer**
- **Ki-67 index**: High proliferation (>20%) predicts worse outcome in breast cancer
- **TP53 mutation**: Poor prognosis across many cancer types
- **Tumor stage/grade**: TNM staging, histologic grade
- **LDH elevation**: Poor prognosis in melanoma, lymphoma
- **AFP elevation**: Poor prognosis in hepatocellular carcinoma
**Cardiovascular**
- **NT-proBNP/BNP**: Elevated levels predict mortality in heart failure
- **Troponin**: Predicts adverse events in ACS
- **CRP**: Inflammation marker, predicts cardiovascular events
**Infectious Disease**
- **HIV viral load**: Predicts disease progression if untreated
- **HCV genotype**: Predicts treatment duration needed
**Application**: Risk stratification, treatment intensity selection, clinical trial enrollment
### Predictive Biomarkers
**Definition**: Identify patients likely to benefit (or not benefit) from specific therapy
**Positive Predictive Biomarkers (Treatment Benefit)**
**Oncology - Targeted Therapy**
- **EGFR exon 19 del/L858R → EGFR TKIs**: Response rate 60-70%, PFS 10-14 months
- **ALK rearrangement → ALK inhibitors**: ORR 70-90%, PFS 25-34 months
- **HER2 amplification → Trastuzumab**: Benefit only in HER2+ (IHC 3+ or FISH+)
- **BRAF V600E → BRAF inhibitors**: ORR 50%, PFS 6-7 months (melanoma)
- **PD-L1 ≥50% → Pembrolizumab**: ORR 45%, PFS 10 months vs 6 months (chemo)
**Oncology - Immunotherapy**
- **MSI-H/dMMR → Anti-PD-1**: ORR 40-60% across tumor types
- **TMB-high → Immunotherapy**: Investigational, some benefit signals
- **PD-L1 expression → Anti-PD-1/PD-L1**: Higher expression correlates with better response
**Hematology**
- **BCR-ABL → Imatinib (CML)**: Complete cytogenetic response 80%
- **CD20+ → Rituximab (lymphoma)**: Benefit only if CD20-expressing cells
- **CD33+ → Gemtuzumab ozogamicin (AML)**: Benefit in CD33+ subset
**Negative Predictive Biomarkers (Resistance/No Benefit)**
- **KRAS mutation → Anti-EGFR mAbs (CRC)**: No benefit, contraindicated
- **EGFR T790M → 1st/2nd-gen TKIs**: Resistance mechanism, use osimertinib
- **RAS/RAF wild-type required → BRAF inhibitors (melanoma)**: Paradoxical MAPK activation
### Diagnostic Biomarkers
**Definition**: Detect or confirm presence of disease
**Infectious Disease**
- **PCR for pathogen DNA/RNA**: SARS-CoV-2, HIV, HCV viral load
- **Antibody titers**: IgM (acute), IgG (prior exposure/immunity)
- **Antigen tests**: Rapid detection (strep, flu, COVID)
**Autoimmune**
- **ANA**: Screen for lupus, connective tissue disease
- **Anti-CCP**: Specific for rheumatoid arthritis
- **Anti-dsDNA**: Lupus, correlates with disease activity
- **ANCA**: Vasculitis (c-ANCA for GPA, p-ANCA for MPA)
**Cancer**
- **PSA**: Prostate cancer screening/monitoring
- **CA 19-9**: Pancreatic cancer, biliary obstruction
- **CEA**: Colorectal cancer monitoring
- **AFP**: Hepatocellular carcinoma, germ cell tumors
### Pharmacodynamic Biomarkers
**Definition**: Assess treatment response or mechanism of action
**Examples**
- **HbA1c**: Glycemic control in diabetes (target <7% typically)
- **LDL cholesterol**: Statin efficacy (target <70 mg/dL in high-risk)
- **Blood pressure**: Antihypertensive efficacy (target <130/80 mmHg)
- **Viral load suppression**: Antiretroviral efficacy (target <20 copies/mL)
- **INR**: Warfarin anticoagulation monitoring (target 2-3 for most indications)
## Genomic Biomarkers
### Mutation Analysis
**Driver Mutations (Oncogenic)**
- **Activating mutations**: Constitutive pathway activation (BRAF V600E, EGFR L858R)
- **Inactivating mutations**: Tumor suppressor loss (TP53, PTEN)
- **Hotspot mutations**: Recurrent positions (KRAS G12/G13, PIK3CA H1047R)
- **Variant allele frequency (VAF)**: Clonality (VAF ≈50% clonal, <10% subclonal)
**Resistance Mutations**
- **EGFR T790M**: Resistance to 1st/2nd-gen TKIs (40-60% of cases)
- **ALK G1202R, I1171N**: Resistance to early ALK inhibitors
- **ESR1 mutations**: Resistance to aromatase inhibitors (breast cancer)
- **RAS mutations**: Acquired resistance to anti-EGFR therapy (CRC)
**Mutation Detection Methods**
- **Tissue NGS**: Comprehensive genomic profiling, 300-500 genes
- **Liquid biopsy**: ctDNA analysis, non-invasive, serial monitoring
- **PCR-based assays**: Targeted hotspot detection, FDA-approved companion diagnostics
- **Allele-specific PCR**: High sensitivity for known mutations (cobas EGFR test)
### Copy Number Variations (CNV)
**Amplifications**
- **HER2 (ERBB2)**: Breast, gastric cancer → trastuzumab, pertuzumab
- Testing: IHC (0, 1+, 2+, 3+) → FISH if 2+ (HER2/CEP17 ratio ≥2.0)
- **MET amplification**: NSCLC resistance mechanism → crizotinib, capmatinib
- Cut-point: Gene copy number ≥5, GCN/CEP7 ratio ≥2.0
- **EGFR amplification**: Glioblastoma, some NSCLC
- **FGFR2 amplification**: Gastric cancer → investigational FGFR inhibitors
**Deletions**
- **PTEN loss**: Common in many cancers, predicts PI3K pathway activation
- **RB1 loss**: Small cell transformation, poor prognosis
- **CDKN2A/B deletion**: Cell cycle dysregulation
- **Homozygous deletion**: Complete loss of both alleles (more significant)
**Detection Methods**
- **FISH (Fluorescence In Situ Hybridization)**: HER2, ALK rearrangements
- **NGS copy number calling**: Depth of coverage analysis
- **SNP array**: Genome-wide CNV detection
- **ddPCR**: Quantitative copy number measurement
### Gene Fusions and Rearrangements
**Oncogenic Fusions**
- **ALK fusions** (NSCLC): EML4-ALK most common (60%), 20+ partners
- Detection: IHC (D5F3 antibody), FISH (break-apart probe), NGS/RNA-seq
- **ROS1 fusions** (NSCLC, glioblastoma): CD74-ROS1, SLC34A2-ROS1, others
- **RET fusions** (NSCLC, thyroid): KIF5B-RET, CCDC6-RET
- **NTRK fusions** (many tumor types, rare): ETV6-NTRK3, others
- Pan-cancer: Larotrectinib, entrectinib approved across tumor types
- **BCR-ABL** (CML, ALL): t(9;22), Philadelphia chromosome
**Fusion Partner Considerations**
- Partner influences drug sensitivity (EML4-ALK variant 3 more sensitive)
- 5' vs 3' fusion affects detection methods
- Intron breakpoints vary (RNA-seq more comprehensive than DNA panels)
**Detection Methods**
- **FISH break-apart probes**: ALK, ROS1, RET
- **IHC**: ALK protein overexpression (screening), ROS1
- **RT-PCR**: Targeted fusion detection
- **RNA-seq**: Comprehensive fusion detection, identifies novel partners
### Tumor Mutational Burden (TMB)
**Definition**: Number of somatic mutations per megabase of DNA
**Classification**
- **TMB-high**: ≥10 mutations/Mb (some definitions ≥20 mut/Mb)
- **TMB-intermediate**: 6-9 mutations/Mb
- **TMB-low**: <6 mutations/Mb
**Clinical Application**
- **Predictive for immunotherapy**: Higher TMB → more neoantigens → better immune response
- **FDA approval**: Pembrolizumab for TMB-H (≥10 mut/Mb) solid tumors (2020)
- **Limitations**: Not validated in all tumor types, assay variability
**Tumor Types with Typically High TMB**
- Melanoma (median 10-15 mut/Mb)
- NSCLC (especially smoking-associated, 8-12 mut/Mb)
- Urothelial carcinoma (8-10 mut/Mb)
- Microsatellite instable tumors (30-50 mut/Mb)
### Microsatellite Instability (MSI) and Mismatch Repair (MMR)
**Classification**
- **MSI-high (MSI-H)**: Instability at ≥2 of 5 loci or ≥30% of markers
- **MSI-low (MSI-L)**: Instability at <2 of 5 loci
- **Microsatellite stable (MSS)**: No instability
**Mismatch Repair Status**
- **dMMR (deficient)**: Loss of MLH1, MSH2, MSH6, or PMS2 by IHC
- **pMMR (proficient)**: Intact expression of all four MMR proteins
**Clinical Significance**
- **MSI-H/dMMR Tumors**: 3-5% of most solid tumors, 15% of colorectal cancer
- **Immunotherapy Sensitivity**: ORR 30-60% to anti-PD-1 therapy
- Pembrolizumab FDA-approved for MSI-H/dMMR solid tumors (2017)
- Nivolumab ± ipilimumab approved
- **Chemotherapy Resistance**: MSI-H CRC does not benefit from 5-FU adjuvant therapy
- **Lynch Syndrome**: Germline MMR mutation if MSI-H + young age + family history
**Testing Algorithm**
```
Colorectal Cancer (all newly diagnosed):
1. IHC for MMR proteins (MLH1, MSH2, MSH6, PMS2)
├─ All intact → pMMR (MSS) → Standard chemotherapy if indicated
│
└─ Loss of one or more → dMMR (likely MSI-H)
└─ Reflex MLH1 promoter hypermethylation test
├─ Methylated → Sporadic MSI-H, immunotherapy option
└─ Unmethylated → Germline testing for Lynch syndrome
```
## Expression Biomarkers
### Immunohistochemistry (IHC)
**PD-L1 Expression (Immune Checkpoint)**
- **Assays**: 22C3 (FDA), 28-8, SP263, SP142 (some differences in scoring)
- **Scoring**: Tumor Proportion Score (TPS) = % tumor cells with membrane staining
- TPS <1%: Low/negative
- TPS 1-49%: Intermediate
- TPS ≥50%: High
- **Combined Positive Score (CPS)**: (PD-L1+ tumor + immune cells) / total tumor cells × 100
- Used for some indications (e.g., CPS ≥10 for pembrolizumab in HNSCC)
**Hormone Receptors (Breast Cancer)**
- **ER/PR Positivity**: ≥1% nuclear staining by IHC (ASCO/CAP guidelines)
- Allred Score 0-8 (proportion + intensity) - historical
- H-score 0-300 (percentage at each intensity) - quantitative
- **Clinical Cut-Points**:
- ER ≥1%: Endocrine therapy indicated
- ER 1-10%: "Low positive," may have lower benefit
- PR loss with ER+: Possible endocrine resistance
**HER2 Testing (Breast/Gastric Cancer)**
```
IHC Initial Test:
├─ 0 or 1+: HER2-negative (no further testing)
│
├─ 2+: Equivocal → Reflex FISH testing
│ ├─ FISH+ (HER2/CEP17 ratio ≥2.0 OR HER2 copies ≥6/cell) → HER2-positive
│ └─ FISH- → HER2-negative
│
└─ 3+: HER2-positive (no FISH needed)
└─ Uniform intense complete membrane staining in >10% of tumor cells
HER2-positive: Trastuzumab-based therapy indicated
HER2-low (IHC 1+ or 2+/FISH-): Trastuzumab deruxtecan eligibility (2022)
```
### RNA Expression Analysis
**Gene Expression Signatures (Breast Cancer)**
**Oncotype DX (21-gene assay)**
- **Recurrence Score (RS)**: 0-100
- RS <26: Low risk → Endocrine therapy alone (most patients)
- RS 26-100: High risk → Chemotherapy + endocrine therapy
- **Population**: ER+/HER2-, node-negative or 1-3 positive nodes
- **Evidence**: TAILORx trial (N=10,273) validated RS <26 can omit chemo
**MammaPrint (70-gene assay)**
- **Result**: High risk vs Low risk (binary)
- **Population**: Early-stage breast cancer, ER+/HER2-
- **Evidence**: MINDACT trial validated low-risk can omit chemo
**Prosigna (PAM50)**
- **Result**: Risk of Recurrence (ROR) score + intrinsic subtype
- **Subtypes**: Luminal A, Luminal B, HER2-enriched, Basal-like
- **Application**: Post-menopausal, ER+, node-negative or 1-3 nodes
**RNA-Seq for Fusion Detection**
- **Advantage**: Detects novel fusion partners, quantifies expression
- **Application**: NTRK fusions (rare, many partners), RET fusions
- **Limitation**: Requires fresh/frozen tissue or good-quality FFPE RNA

### Testing Recommendations by Tumor Type
**NSCLC (NCCN Guidelines)**
```
Broad molecular profiling for all advanced NSCLC at diagnosis:
Required (FDA-approved therapies available):
✓ EGFR mutations (exons 18, 19, 20, 21)
✓ ALK rearrangement
✓ ROS1 rearrangement
✓ BRAF V600E
✓ MET exon 14 skipping
✓ RET rearrangements
✓ NTRK fusions
✓ KRAS G12C
✓ PD-L1 IHC
Recommended (to inform treatment strategy):
✓ Comprehensive NGS panel (captures all above + emerging targets)
✓ Consider liquid biopsy if tissue insufficient
At progression on targeted therapy:
✓ Repeat tissue biopsy or liquid biopsy for resistance mechanisms
✓ Examples: EGFR T790M, ALK resistance mutations, MET amplification
```
**Metastatic Colorectal Cancer**
```
Required before anti-EGFR therapy (cetuximab, panitumumab):
✓ RAS testing (KRAS exons 2, 3, 4; NRAS exons 2, 3, 4)
└─ RAS mutation → Do NOT use anti-EGFR therapy (resistance)
✓ BRAF V600E
└─ If BRAF V600E+ → Consider encorafenib + cetuximab + binimetinib
Recommended for all metastatic CRC:
✓ MSI/MMR testing (immunotherapy indication)
✓ HER2 amplification (investigational trastuzumab-based therapy if RAS/BRAF WT)
✓ NTRK fusions (rare, <1%, but actionable)
Left-sided vs Right-sided:
- Left-sided (descending, sigmoid, rectum): Better prognosis, anti-EGFR more effective
- Right-sided (cecum, ascending): Worse prognosis, anti-EGFR less effective, consider bevacizumab
```
**Melanoma**
```
All advanced melanoma:
✓ BRAF V600 mutation (30-50% of cutaneous melanoma)
└─ If BRAF V600E/K → Dabrafenib + trametinib or vemurafenib + cobimetinib
✓ NRAS mutation (20-30%)
└─ No targeted therapy approved, consider MEK inhibitor trials
✓ KIT mutations (mucosal, acral, chronic sun-damaged melanoma)
└─ If KIT exon 11 or 13 mutation → Imatinib (off-label)
✓ PD-L1 (optional, not required for immunotherapy eligibility)
Note: Uveal melanoma has different biology (GNAQ, GNA11 mutations)
```
## Biomarker Cut-Points and Thresholds
### Establishing Clinical Cut-Points
**Methods for Cut-Point Determination**
**Data-Driven Approaches**
- **Median split**: Simple but arbitrary, may not be optimal
- **Tertiles/quartiles**: Categorizes into 3-4 groups
- **ROC curve analysis**: Maximizes sensitivity and specificity
- **Maximally selected rank statistics**: Finds optimal prognostic cut-point
- **Validation required**: Independent cohort confirmation essential
**Biologically Informed**
- **Detection limit**: Assay lower limit of quantification
- **Mechanism-based**: Threshold for pathway activation
- **Pharmacodynamic**: Threshold for target engagement
- **Normal range**: Comparison to healthy individuals
**Clinically Defined**
- **Guideline-recommended**: Established by professional societies
- **Regulatory-approved**: FDA-specified threshold for companion diagnostic
- **Trial-defined**: Cut-point used in pivotal clinical trial
**PD-L1 Example**
- **Cut-points**: 1%, 5%, 10%, 50% TPS used in different trials
- **Context-dependent**: Varies by drug, disease, line of therapy
- **≥50%**: Pembrolizumab monotherapy (KEYNOTE-024)
- **≥1%**: Atezolizumab combinations, broader population
### Continuous vs Categorical
**Continuous Analysis Advantages**
- Preserves information (no dichotomization loss)
- Statistical power maintained
- Can assess dose-response relationship
- HR per unit increase or per standard deviation
**Categorical Analysis Advantages**
- Clinically interpretable (high vs low)
- Facilitates treatment decisions (binary: use targeted therapy yes/no)
- Aligns with regulatory approvals (biomarker-positive = eligible)
**Best Practice**: Report both continuous and categorical analyses
- Cox model with continuous biomarker
- Stratified analysis by clinically relevant cut-point
- Subgroup analysis to confirm consistency
## Germline vs Somatic Testing
### Germline (Inherited) Mutations
**Indications for Germline Testing**
- **Cancer predisposition syndromes**: BRCA1/2, Lynch syndrome (MLH1, MSH2), Li-Fraumeni (TP53)
- **Family history**: Multiple affected relatives, young age at diagnosis
- **Tumor features**: MSI-H in young patient, triple-negative breast cancer <60 years
- **Treatment implications**: PARP inhibitors for BRCA-mutated (germline or somatic)
**Common Hereditary Cancer Syndromes**
- **BRCA1/2**: Breast, ovarian, pancreatic, prostate cancer
- Testing: All ovarian cancer, TNBC <60 years, male breast cancer
- Treatment: PARP inhibitors (olaparib, talazoparib)
- Prevention: Prophylactic mastectomy, oophorectomy (risk-reducing)
- **Lynch syndrome (MLH1, MSH2, MSH6, PMS2)**: Colorectal, endometrial, ovarian, gastric
- Testing: MSI-H/dMMR tumors, Amsterdam II criteria families
- Surveillance: Colonoscopy every 1-2 years starting age 20-25
- **Li-Fraumeni (TP53)**: Diverse cancers at young age
- **PTEN (Cowden syndrome)**: Breast, thyroid, endometrial cancer
**Genetic Counseling**
- Pre-test counseling: Implications for patient and family
- Post-test counseling: Management, surveillance, family testing
- Informed consent: Genetic discrimination concerns (GINA protections)
### Somatic (Tumor-Only) Testing
**Tumor Tissue Testing**
- Detects mutations present in cancer cells only (not inherited)
- Most cancer driver mutations are somatic (KRAS, EGFR in lung cancer)
- No implications for family members
- Guides therapy selection
**Distinguishing Germline from Somatic**
- **Variant allele frequency**: Germline ~50% (heterozygous) or ~100% (homozygous); somatic variable
- **Matched normal**: Paired tumor-normal sequencing definitive
- **Databases**: Germline variant databases (gnomAD, ClinVar)
- **Reflex germline testing**: Trigger testing if pathogenic germline variant suspected

## Clinical Decision Trees
### Diagnostic Algorithms
**Chest Pain Evaluation Algorithm**
```
Entry: Patient with chest pain
├─ STEMI Criteria? (ST elevation ≥1mm in ≥2 contiguous leads)
│ ├─ YES → Activate cath lab, aspirin 325mg, heparin, clopidogrel 600mg
│ │ Transfer for primary PCI (goal door-to-balloon <90 minutes)
│ └─ NO → Continue evaluation
├─ High-Risk Features? (Hemodynamic instability, arrhythmia, troponin elevation)
│ ├─ YES → Admit CCU, serial troponins, cardiology consultation
│ │ Consider early angiography if NSTEMI
│ └─ NO → Calculate TIMI or HEART score
├─ TIMI Score 0-1 or HEART Score 0-3? (Low risk)
│ ├─ YES → Observe 6-12 hours, serial troponins, stress test if negative
│ │ Discharge if all negative with cardiology follow-up in 72 hours
│ └─ NO → TIMI 2-4 or HEART 4-6 (Intermediate risk)
├─ TIMI Score 2-4 or HEART Score 4-6? (Intermediate risk)
│ ├─ YES → Admit telemetry, serial troponins, stress imaging vs CT angiography
│ │ Medical management: Aspirin, statin, beta-blocker
│ └─ NO → TIMI ≥5 or HEART ≥7 (High risk) → Treat as NSTEMI
Decision Endpoint: Risk-stratified pathway with 30-day event rate documented
```
**Pulmonary Embolism Diagnostic Algorithm (Wells Criteria)**
```
Entry: Suspected PE
Step 1: Calculate Wells Score
Clinical features points:
- Clinical signs of DVT: 3 points
- PE more likely than alternative diagnosis: 3 points
- Heart rate >100: 1.5 points
- Immobilization/surgery in past 4 weeks: 1.5 points
- Previous PE/DVT: 1.5 points
- Hemoptysis: 1 point
- Malignancy: 1 point
Step 2: Risk Stratify
├─ Wells Score ≤4 (PE unlikely)
│ └─ D-dimer test
│ ├─ D-dimer negative (<500 ng/mL) → PE excluded, consider alternative diagnosis
│ └─ D-dimer positive (≥500 ng/mL) → CTPA
│
└─ Wells Score >4 (PE likely)
└─ CTPA (skip D-dimer)
Step 3: CTPA Results
├─ Positive for PE → Risk stratify severity
│ ├─ Massive PE (hypotension, shock) → Thrombolytics vs embolectomy
│ ├─ Submassive PE (RV strain, troponin+) → Admit ICU, consider thrombolytics
│ └─ Low-risk PE → Anticoagulation, consider outpatient management
│
└─ Negative for PE → PE excluded, investigate alternative diagnosis
Step 4: Treatment Decision (if PE confirmed)
├─ Absolute contraindication to anticoagulation?
│ ├─ YES → IVC filter placement, treat underlying condition
│ └─ NO → Anticoagulation therapy
│
├─ Cancer-associated thrombosis?
│ ├─ YES → LMWH preferred (edoxaban alternative)
│ └─ NO → DOAC preferred (apixaban, rivaroxaban, edoxaban)
│
└─ Duration: Minimum 3 months, extended if unprovoked or recurrent
```
### Treatment Selection Algorithms
**NSCLC First-Line Treatment Algorithm**
```
Entry: Advanced/Metastatic NSCLC, adequate PS (ECOG 0-2)
Step 1: Biomarker Testing Complete?
├─ NO → Reflex testing: EGFR, ALK, ROS1, BRAF, PD-L1, consider NGS
│ Hold systemic therapy pending results (unless rapidly progressive)
└─ YES → Proceed to Step 2
Step 2: Actionable Genomic Alteration?
├─ EGFR exon 19 deletion or L858R → Osimertinib 80mg daily
│ └─ Alternative: Erlotinib, gefitinib, afatinib (less preferred)
│
├─ ALK rearrangement → Alectinib 600mg BID
│ └─ Alternatives: Brigatinib, lorlatinib, crizotinib (less preferred)
│

## GRADE Methodology
### Assessing Quality of Evidence
**Initial Quality Assignment**
**Randomized Controlled Trials**: Start at HIGH quality (⊕⊕⊕⊕)
**Observational Studies**: Start at LOW quality (⊕⊕○○)
### Factors Decreasing Quality (Downgrade)
**Risk of Bias** (-1 or -2 levels)
- Lack of allocation concealment
- Lack of blinding
- Incomplete outcome data
- Selective outcome reporting
- Other sources of bias
**Inconsistency** (-1 or -2 levels)
- Unexplained heterogeneity in results across studies
- Wide variation in effect estimates
- Non-overlapping confidence intervals
- High I² statistic in meta-analysis (>50-75%)
**Indirectness** (-1 or -2 levels)
- Different population than target (younger patients in trials, applying to elderly)
- Different intervention (higher dose in trial than used in practice)
- Different comparator (placebo in trial, comparing to active treatment)
- Surrogate outcomes (PFS) when interested in survival (OS)
**Imprecision** (-1 or -2 levels)
- Wide confidence intervals crossing threshold of benefit/harm
- Small sample size, few events
- Optimal information size (OIS) not met
- Rule of thumb: <300 events for continuous outcomes, <200 events for dichotomous
**Publication Bias** (-1 level)
- Funnel plot asymmetry (if ≥10 studies)
- Known unpublished studies with negative results
- Selective outcome reporting
- Industry-sponsored studies only
### Factors Increasing Quality (Upgrade - Observational Only)
**Large Magnitude of Effect** (+1 or +2 levels)
- +1: RR >2 or <0.5 (moderate effect)
- +2: RR >5 or <0.2 (large effect)
- No plausible confounders would reduce effect
**Dose-Response Gradient** (+1 level)
- Clear dose-response or duration-response relationship
- Strengthens causal inference
**All Plausible Confounders Would Reduce Effect** (+1 level)
- Observed effect despite confounders biasing toward null
- Rare, requires careful justification
### Final Quality Rating
After adjustments, assign final quality:
- **High (⊕⊕⊕⊕)**: Very confident in effect estimate
- **Moderate (⊕⊕⊕○)**: Moderately confident; true effect likely close to estimate
- **Low (⊕⊕○○)**: Limited confidence; true effect may be substantially different
- **Very Low (⊕○○○)**: Very little confidence; true effect likely substantially different
## Systematic Reviews and Meta-Analyses
### PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses)
**Search Strategy**
- **Databases**: PubMed/MEDLINE, Embase, Cochrane Library, Web of Science
- **Search Terms**: PICO (Population, Intervention, Comparator, Outcome)
- **Date Range**: Typically last 10-20 years or comprehensive
- **Language**: English only or all languages with translation
- **Grey Literature**: Conference abstracts, trial registries, unpublished data
**Study Selection**
```

Studies included in meta-analysis (n=24) - Wrong intervention (n=35)
- No outcomes reported (n=28)
- Duplicate data (n=18)
- Poor quality (n=10)
```
**Data Extraction**
- Study characteristics: Design, sample size, population, intervention
- Results: Outcomes, effect sizes, confidence intervals, p-values
- Quality assessment: Risk of bias tool (Cochrane RoB 2.0 for RCTs)
- Dual extraction: Two reviewers independently, resolve disagreements
### Meta-Analysis Methods
**Fixed-Effect Model**
- **Assumption**: Single true effect size shared by all studies
- **Weighting**: By inverse variance (larger studies have more weight)
- **Application**: When heterogeneity is low (I² <25%)
- **Interpretation**: Estimate of common effect across studies
**Random-Effects Model**
- **Assumption**: True effect varies across studies (distribution of effects)
- **Weighting**: By inverse variance + between-study variance
- **Application**: When heterogeneity moderate to high (I² ≥25%)
- **Interpretation**: Estimate of average effect (center of distribution)
- **Wider CI**: Accounts for heterogeneity, more conservative
**Heterogeneity Assessment**
**I² Statistic**
- Percentage of variability due to heterogeneity rather than chance
- I² = 0-25%: Low heterogeneity
- I² = 25-50%: Moderate heterogeneity
- I² = 50-75%: Substantial heterogeneity
- I² = 75-100%: Considerable heterogeneity
**Q Test (Cochran's Q)**
- Test for heterogeneity
- p<0.10 suggests significant heterogeneity (liberal threshold)
- Low power when few studies, use I² as primary measure
**Tau² (τ²)**
- Estimate of between-study variance
- Used in random-effects weighting
**Subgroup Analysis**
- Explore sources of heterogeneity
- Pre-specified subgroups: Disease stage, biomarker status, treatment regimen
- Test for interaction between subgroups
**Forest Plot Interpretation**

**Cancer Registries**
- **SEER (Surveillance, Epidemiology, and End Results)**: US cancer registry
- **NCDB (National Cancer Database)**: Hospital registry data
- Population-level survival, treatment patterns
- Limited treatment detail, no toxicity data
**Prospective Cohorts**
- Framingham Heart Study, Nurses' Health Study
- Long-term follow-up, rich covariate data
- Expensive, time-consuming
### RWE Applications
**Comparative Effectiveness**
- Compare treatments in real-world settings (less strict eligibility than RCTs)
- Complement RCT data with broader populations
- Example: Effectiveness of immunotherapy in elderly, poor PS patients excluded from trials
**Safety Signal Detection**
- Rare adverse events not detected in trials
- Long-term toxicities
- Drug-drug interactions in polypharmacy
- Postmarketing surveillance
**Treatment Patterns and Access**
- Guideline adherence in community practice
- Time to treatment initiation
- Disparities in care delivery
- Off-label use prevalence
**Limitations of RWE**
- **Confounding by indication**: Sicker patients receive more aggressive treatment
- **Immortal time bias**: Time between events affecting survival estimates
- **Missing data**: Incomplete or inconsistent data collection
- **Causality**: Association does not prove causation without randomization
**Strengthening RWE**
- **Propensity score matching**: Balance baseline characteristics between groups
- **Multivariable adjustment**: Adjust for measured confounders in Cox model
- **Sensitivity analyses**: Test robustness to unmeasured confounding
- **Instrumental variables**: Use natural experiments to approximate randomization
## Meta-Analysis Techniques
### Binary Outcomes (Response Rate, Event Rate)
**Effect Measures**
- **Risk Ratio (RR)**: Ratio of event probabilities
- **Odds Ratio (OR)**: Ratio of odds (less intuitive)
- **Risk Difference (RD)**: Absolute difference in event rates
**Example Calculation**
```
Study 1:
- Treatment A: 30/100 responded (30%)
- Treatment B: 15/100 responded (15%)
- RR = 0.30/0.15 = 2.0 (95% CI 1.15-3.48)
- RD = 0.30 - 0.15 = 0.15 or 15% (95% CI 4.2%-25.8%)
- NNT = 1/RD = 1/0.15 = 6.7 (treat 7 patients to get 1 additional response)
```
**Pooling Methods**
- **Mantel-Haenszel**: Common fixed-effect method
- **DerSimonian-Laird**: Random-effects method
- **Peto**: For rare events (event rate <1%)
### Time-to-Event Outcomes (Survival, PFS)
**Hazard Ratio Pooling**
- Extract HR and 95% CI (or log(HR) and SE) from each study
- Weight by inverse variance
- Pool using generic inverse variance method
- Report pooled HR with 95% CI, heterogeneity statistics
**When HR Not Reported**
- Extract from Kaplan-Meier curves (Parmar method, digitizing software)
- Calculate from log-rank p-value and event counts
- Request from study authors
### Continuous Outcomes (Quality of Life, Lab Values)
**Standardized Mean Difference (SMD)**
- Application: Different scales used across studies
- SMD = (Mean₁ - Mean₂) / Pooled SD
- Interpretation: Cohen's d effect size (0.2 small, 0.5 medium, 0.8 large)
**Mean Difference (MD)**
- Application: Same scale/unit used across studies
- MD = Mean₁ - Mean₂
- More directly interpretable than SMD
## Network Meta-Analysis
### Purpose
Compare multiple treatments simultaneously when no head-to-head trials exist
**Example Scenario**
- Drug A vs placebo (Trial 1)
- Drug B vs placebo (Trial 2)
- Drug C vs Drug A (Trial 3)
- **Question**: How does Drug B compare to Drug C? (no direct comparison)
### Methods
**Fixed-Effect Network Meta-Analysis**
- Assumes consistency (transitivity): A vs B effect = (A vs C effect) - (B vs C effect)
- Provides indirect comparison estimates
- Ranks treatments by P-score or SUCRA
**Random-Effects Network Meta-Analysis**
- Allows heterogeneity between studies
- More conservative estimates
**Consistency Checking**
- Compare direct vs indirect evidence for same comparison
- Node-splitting analysis
- Loop consistency (if closed loops in network)
### Interpretation Cautions
- **Transitivity assumption**: May not hold if studies differ in important ways
- **Indirect evidence**: Less reliable than direct head-to-head trials
- **Rankings**: Probabilistic, not definitive ordering
- **Clinical judgment**: Consider beyond statistical rankings
## Evidence Tables
### Constructing Evidence Summary Tables
**PICO Framework**
- **P (Population)**: Patient characteristics, disease stage, biomarker status
- **I (Intervention)**: Treatment regimen, dose, schedule
- **C (Comparator)**: Control arm (placebo, standard of care)

```
## Quality Assessment Tools
### RCT Quality Assessment (Cochrane Risk of Bias 2.0)
**Domains**
1. **Bias from randomization process**: Sequence generation, allocation concealment
2. **Bias from deviations from intended interventions**: Blinding, protocol adherence
3. **Bias from missing outcome data**: Attrition, intention-to-treat analysis
4. **Bias in outcome measurement**: Blinded assessment, objective outcomes
5. **Bias in selection of reported result**: Selective reporting, outcome switching
**Judgment**: Low risk, some concerns, high risk (for each domain)
**Overall Risk of Bias**: Based on highest-risk domain
### Observational Study Quality (Newcastle-Ottawa Scale)
**Selection (max 4 stars)**
- Representativeness of exposed cohort
- Selection of non-exposed cohort
- Ascertainment of exposure
- Outcome not present at start
**Comparability (max 2 stars)**
- Comparability of cohorts (design/analysis adjustment for confounders)
**Outcome (max 3 stars)**
- Assessment of outcome
- Follow-up duration adequate
- Adequacy of follow-up (low attrition)
**Total Score**: 0-9 stars
- **High quality**: 7-9 stars
- **Moderate quality**: 4-6 stars
- **Low quality**: 0-3 stars
## Translating Evidence to Recommendations
### Recommendation Development Process
**Step 1: PICO Question Formulation**
```
Example PICO:
P - Population: Adults with type 2 diabetes and cardiovascular disease
I - Intervention: SGLT2 inhibitor (empagliflozin)
C - Comparator: Placebo (added to standard care)
O - Outcomes: Major adverse cardiovascular events (3P-MACE), hospitalization for heart failure
```
**Step 2: Systematic Evidence Review**
- Identify all relevant studies
- Assess quality using standardized tools
- Extract outcome data
- Synthesize findings (narrative or meta-analysis)
**Step 3: GRADE Evidence Rating**
- Start at high (RCTs) or low (observational)
- Downgrade for risk of bias, inconsistency, indirectness, imprecision, publication bias
- Upgrade for large effect, dose-response, confounders reducing effect (observational only)
- Assign final quality rating
**Step 4: Recommendation Strength Determination**
**Strong Recommendation (Grade 1)**
- Desirable effects clearly outweigh undesirable effects
- High or moderate quality evidence
- Little variability in patient values
- Intervention cost-effective
**Conditional Recommendation (Grade 2)**
- Trade-offs: Desirable and undesirable effects closely balanced
- Low or very low quality evidence
- Substantial variability in patient values/preferences
- Uncertain cost-effectiveness
**Step 5: Wording the Recommendation**
```
Strong: "We recommend..."
Example: "We recommend SGLT2 inhibitor therapy for adults with type 2 diabetes and
established cardiovascular disease to reduce risk of hospitalization for heart failure
and cardiovascular death (Strong recommendation, high-quality evidence - GRADE 1A)."
Conditional: "We suggest..."
Example: "We suggest considering GLP-1 receptor agonist therapy for adults with type 2
diabetes and CKD to reduce risk of kidney disease progression (Conditional recommendation,
moderate-quality evidence - GRADE 2B)."
```
## Incorporating Emerging Evidence
### Early-Phase Trial Data
**Phase 1 Trials**
- Purpose: Dose-finding, safety
- Outcomes: Maximum tolerated dose (MTD), dose-limiting toxicities (DLTs), pharmacokinetics
- Evidence level: Very low (expert opinion, case series)
- Clinical application: Investigational only, clinical trial enrollment
**Phase 2 Trials**
- Purpose: Preliminary efficacy signal
- Design: Single-arm (ORR primary endpoint) or randomized (PFS comparison)
- Evidence level: Low to moderate
- Clinical application: May support off-label use in refractory settings, clinical trial enrollment preferred
**Phase 3 Trials**
- Purpose: Confirmatory efficacy and safety
- Design: Randomized controlled trial, OS or PFS primary endpoint
- Evidence level: High (if well-designed and executed)
- Clinical application: Regulatory approval basis, guideline recommendations
**Phase 4 Trials**
- Purpose: Post-marketing surveillance, additional indications
- Evidence level: Variable (depends on design)
- Clinical application: Safety monitoring, expanded usage
### Breakthrough Therapy Designation
**FDA Fast-Track Programs**
- **Breakthrough Therapy**: Preliminary evidence of substantial improvement over existing therapy
- **Accelerated Approval**: Approval based on surrogate endpoint (PFS, ORR)
- Post-marketing requirement: Confirmatory OS trial
- **Priority Review**: Shortened FDA review time (6 vs 10 months)
**Implications for Guidelines**
- May receive NCCN Category 2A before phase 3 data mature
- Upgrade to Category 1 when confirmatory data published
- Monitor for post-market confirmatory trial results
### Updating Recommendations
**Triggers for Update**

# Outcome Analysis and Statistical Methods Guide
## Overview
Rigorous outcome analysis is essential for clinical decision support documents. This guide covers survival analysis, response assessment, statistical testing, and data visualization for patient cohort analyses and treatment evaluation.
## Survival Analysis
### Kaplan-Meier Method
**Overview**
- Non-parametric estimator of survival function from time-to-event data
- Handles censored observations (patients alive at last follow-up)
- Provides survival probability at each time point
- Generates characteristic step-function survival curves
**Key Concepts**
**Censoring**
- **Right censoring**: Most common - patient alive at last follow-up or study end
- **Left censoring**: Rare in clinical studies
- **Interval censoring**: Event occurred between two assessment times
- **Informative vs non-informative**: Censoring should be independent of outcome
**Survival Function S(t)**
- S(t) = Probability of surviving beyond time t
- S(0) = 1.0 (100% alive at time zero)
- S(t) decreases as time increases
- Step decreases at each event time
**Median Survival**
- Time point where S(t) = 0.50
- 50% of patients alive, 50% have had event
- Reported with 95% confidence interval
- "Not reached (NR)" if fewer than 50% events
**Survival Rates at Fixed Time Points**
- 1-year survival rate, 2-year survival rate, 5-year survival rate
- Read from K-M curve at specific time point
- Report with 95% CI: S(t) ± 1.96 × SE
**Calculation Example**
```
Time Events At Risk Survival Probability
0 0 100 1.000
3 2 100 0.980 (98/100)
5 1 95 0.970 (97/100 × 95/98)
8 3 87 0.936 (94/100 × 92/95 × 84/87)
...
```
### Log-Rank Test
**Purpose**: Compare survival curves between two or more groups
**Null Hypothesis**: No difference in survival distributions between groups
**Test Statistic**
- Compares observed vs expected events in each group at each time point
- Weights all time points equally
- Follows chi-square distribution with df = k-1 (k groups)
**Reporting**
- Chi-square statistic, degrees of freedom, p-value
- Example: χ² = 6.82, df = 1, p = 0.009
- Interpretation: Significant difference in survival curves
**Assumptions**
- Censoring is non-informative and independent
- Proportional hazards (constant HR over time)
- If non-proportional, consider time-varying effects
**Alternatives for Non-Proportional Hazards**
- **Gehan-Breslow test**: Weights early events more heavily
- **Peto-Peto test**: Modifies Gehan-Breslow weighting
- **Restricted mean survival time (RMST)**: Difference in area under K-M curve
### Cox Proportional Hazards Regression
**Purpose**: Multivariable survival analysis, estimate hazard ratios adjusting for covariates
**Model**: h(t|X) = h₀(t) × exp(β₁X₁ + β₂X₂ + ... + βₚXₚ)
- h(t|X): Hazard rate for individual with covariates X
- h₀(t): Baseline hazard function (unspecified)
- exp(β): Hazard ratio for one-unit change in covariate
**Hazard Ratio Interpretation**
- HR = 1.0: No effect
- HR > 1.0: Increased risk (harmful)
- HR < 1.0: Decreased risk (beneficial)
- HR = 0.50: 50% reduction in hazard (risk of event)
**Example Output**
```
Variable HR 95% CI p-value
Treatment (B vs A) 0.62 0.43-0.89 0.010
Age (per 10 years) 1.15 1.02-1.30 0.021
ECOG PS (2 vs 0-1) 1.85 1.21-2.83 0.004
Biomarker+ (vs -) 0.71 0.48-1.05 0.089
```
**Proportional Hazards Assumption**
- Hazard ratio constant over time
- Test: Schoenfeld residuals, log-minus-log plots
- Violation: Time-varying effects, consider stratification or time-dependent covariates
**Multivariable vs Univariable**
- **Univariable**: One covariate at a time, unadjusted HRs
- **Multivariable**: Multiple covariates simultaneously, adjusted HRs
- Report both: Univariable for all variables, multivariable for final model
**Model Selection**
- **Forward selection**: Start with empty model, add significant variables
- **Backward elimination**: Start with all variables, remove non-significant
- **Clinical judgment**: Include known prognostic factors regardless of p-value
- **Parsimony**: Avoid overfitting, rule of thumb 1 variable per 10-15 events
## Response Assessment
### RECIST v1.1 (Response Evaluation Criteria in Solid Tumors)
**Target Lesions**
- Select up to 5 lesions total (maximum 2 per organ)
- Measurable: ≥10 mm longest diameter (≥15 mm for lymph nodes short axis)
- Sum of longest diameters (SLD) at baseline
**Response Categories**
**Complete Response (CR)**
- Disappearance of all target and non-target lesions
- Lymph nodes must regress to <10 mm short axis
- Confirmation required at ≥4 weeks
**Partial Response (PR)**
- ≥30% decrease in SLD from baseline
- No new lesions or unequivocal progression of non-target lesions
- Confirmation required at ≥4 weeks
**Stable Disease (SD)**
- Neither PR nor PD criteria met
- Minimum duration typically 6-8 weeks from baseline
**Progressive Disease (PD)**
- ≥20% increase in SLD AND ≥5 mm absolute increase from smallest SLD (nadir)
- OR appearance of new lesions
- OR unequivocal progression of non-target lesions
**Example Calculation**
```
Baseline SLD: 80 mm (4 target lesions)
Week 6 SLD: 52 mm
Percent change: (52 - 80)/80 × 100% = -35%
Classification: Partial Response (≥30% decrease)
Week 12 SLD: 48 mm (nadir)
Week 18 SLD: 62 mm
Percent change from nadir: (62 - 48)/48 × 100% = +29%
Absolute change: 62 - 48 = 14 mm
Classification: Progressive Disease (>20% AND ≥5 mm increase)
```
### iRECIST (Immune RECIST)
**Purpose**: Account for atypical response patterns with immunotherapy
**Modifications from RECIST v1.1**
**iUPD (Immune Unconfirmed Progressive Disease)**
- Initial increase in tumor burden or new lesions
- Requires confirmation at next assessment (≥4 weeks later)
- Continue treatment if clinically stable
**iCPD (Immune Confirmed Progressive Disease)**
- Confirmed progression at repeat imaging
- Discontinue immunotherapy
**Pseudoprogression**
- Initial apparent progression followed by response
- Mechanism: Immune cell infiltration increases tumor size
- Incidence: 5-10% of patients on immunotherapy
- Management: Continue treatment if patient clinically stable
**New Lesions**
- Record size and location but continue treatment
- Do not automatically classify as PD
- Confirm progression if new lesions grow or additional new lesions appear
### Other Response Criteria
**Lugano Classification (Lymphoma)**
- **PET-based**: Deauville 5-point scale
- Score 1-3: Negative (metabolic CR)
- Score 4-5: Positive (residual disease)
- **CT-based**: If PET not available
- **Bone marrow**: Required for staging in some lymphomas
**RANO (Response Assessment in Neuro-Oncology)**
- **Glioblastoma-specific**: Accounts for pseudoprogression with radiation/temozolomide
- **Enhancing disease**: Bidimensional measurements (product of perpendicular diameters)
- **Non-enhancing disease**: FLAIR changes assessed separately
- **Corticosteroid dose**: Must document, increase may indicate progression
**mRECIST (Modified RECIST for HCC)**
- **Viable tumor**: Enhancing portion only (arterial phase enhancement)
- **Necrosis**: Non-enhancing areas excluded from measurements
- **Application**: Hepatocellular carcinoma with arterial enhancement
## Outcome Metrics
### Efficacy Endpoints
**Overall Survival (OS)**
- **Definition**: Time from randomization/treatment start to death from any cause
- **Advantages**: Objective, not subject to assessment bias, regulatory gold standard
- **Disadvantages**: Requires long follow-up, affected by subsequent therapies
- **Censoring**: Last known alive date
- **Analysis**: Kaplan-Meier, log-rank test, Cox regression
**Progression-Free Survival (PFS)**
- **Definition**: Time from randomization to progression (RECIST) or death
- **Advantages**: Earlier readout than OS, direct treatment effect
- **Disadvantages**: Requires regular imaging, subject to assessment timing
- **Censoring**: Last tumor assessment without progression
- **Sensitivity Analysis**: Assess impact of censoring assumptions
**Objective Response Rate (ORR)**
- **Definition**: Proportion of patients achieving CR or PR (best response)
- **Denominator**: Evaluable patients (baseline measurable disease)
- **Reporting**: Percentage with 95% CI (exact binomial method)
- **Duration**: Time from first response to progression (DOR)
- **Advantage**: Binary endpoint, no censoring complications
**Disease Control Rate (DCR)**
- **Definition**: CR + PR + SD (stable disease ≥6-8 weeks)
- **Less Stringent**: Captures clinical benefit beyond objective response
- **Reporting**: Percentage with 95% CI
**Duration of Response (DOR)**
- **Definition**: Time from first CR or PR to progression (among responders only)
- **Population**: Subset analysis of responders
- **Analysis**: Kaplan-Meier among responders
- **Reporting**: Median DOR with 95% CI
**Time to Treatment Failure (TTF)**
- **Definition**: Time from start to discontinuation for any reason (progression, toxicity, death, patient choice)
- **Advantage**: Reflects real-world treatment duration
- **Components**: PFS + toxicity-related discontinuations
### Safety Endpoints
**Adverse Events (CTCAE v5.0)**
**Grading**
- **Grade 1**: Mild, asymptomatic or mild symptoms, clinical intervention not indicated
- **Grade 2**: Moderate, minimal/local intervention indicated, age-appropriate ADL limitation
- **Grade 3**: Severe or medically significant, not immediately life-threatening, hospitalization/prolongation indicated, disabling, self-care ADL limitation
- **Grade 4**: Life-threatening consequences, urgent intervention indicated
- **Grade 5**: Death related to adverse event
**Reporting Standards**

**Serious Adverse Events (SAEs)**
- SAE incidence and type
- Relationship to treatment (related vs unrelated)
- Outcome (resolved, ongoing, fatal)
- Causality assessment (definite, probable, possible, unlikely, unrelated)
**Treatment Modifications**
- Dose reductions: n (%), reason
- Dose delays: n (%), duration
- Discontinuations: n (%), reason (toxicity vs progression vs other)
- Relative dose intensity: (actual dose delivered / planned dose) × 100%
## Statistical Analysis Methods
### Comparing Continuous Outcomes
**Independent Samples t-test**
- **Application**: Compare means between two independent groups (normally distributed)
- **Assumptions**: Normal distribution, equal variances (or use Welch's t-test)
- **Reporting**: Mean ± SD for each group, mean difference (95% CI), t-statistic, df, p-value
- **Example**: Mean age 62.3 ± 8.4 vs 58.7 ± 9.1 years, difference 3.6 years (95% CI 0.2-7.0, p=0.038)
**Mann-Whitney U Test (Wilcoxon Rank-Sum)**
- **Application**: Compare medians between two groups (non-normal distribution)
- **Non-parametric**: No distributional assumptions
- **Reporting**: Median [IQR] for each group, median difference, U-statistic, p-value
- **Example**: Median time to response 6.2 [4.1-8.3] vs 8.5 [5.9-11.2] weeks, p=0.042
**ANOVA (Analysis of Variance)**
- **Application**: Compare means across three or more groups
- **Output**: F-statistic, p-value (overall test)
- **Post-hoc**: If significant, pairwise comparisons with Tukey or Bonferroni correction
- **Example**: Treatment effect varied by biomarker subgroup (F=4.32, df=2, p=0.016)
### Comparing Categorical Outcomes
**Chi-Square Test for Independence**
- **Application**: Compare proportions between two or more groups
- **Assumptions**: Expected count ≥5 in at least 80% of cells
- **Reporting**: n (%) for each cell, χ², df, p-value
- **Example**: ORR 45% vs 30%, χ²=6.21, df=1, p=0.013
**Fisher's Exact Test**
- **Application**: 2×2 tables when expected count <5
- **Exact p-value**: No large-sample approximation
- **Two-sided vs one-sided**: Typically report two-sided
- **Example**: SAE rate 3/20 (15%) vs 8/22 (36%), Fisher's exact p=0.083
**McNemar's Test**
- **Application**: Paired categorical data (before/after, matched pairs)
- **Example**: Response before vs after treatment switch in same patients
### Sample Size and Power
**Power Analysis Components**
- **Alpha (α)**: Type I error rate, typically 0.05 (two-sided)
- **Beta (β)**: Type II error rate, typically 0.10 or 0.20
- **Power**: 1 - β, typically 0.80 or 0.90 (80-90% power)
- **Effect size**: Expected difference (HR, mean difference, proportion difference)
- **Sample size**: Number of patients or events needed
**Survival Study Sample Size**
- Events-driven: Need sufficient events (deaths, progressions)
- Rule of thumb: 80% power requires approximately 165 events for HR=0.70 (α=0.05, two-sided)
- Accrual time + follow-up time determines calendar time
**Response Rate Study**
```
Example: Detect ORR difference 45% vs 30% (15 percentage points)
- α = 0.05 (two-sided)
- Power = 0.80
- Sample size: n = 94 per group (188 total)
- With 10% dropout: n = 105 per group (210 total)
```

## Confidence Intervals
### Interpretation
**95% Confidence Interval**
- Range of plausible values for true population parameter
- If study repeated 100 times, 95 of the 95% CIs would contain true value
- **Not**: 95% probability true value within this interval (frequentist, not Bayesian)
**Relationship to p-value**
- If 95% CI excludes null value (HR=1.0, difference=0), p<0.05
- If 95% CI includes null value, p≥0.05
- CI provides more information: magnitude and precision of effect
**Precision**
- **Narrow CI**: High precision, large sample size
- **Wide CI**: Low precision, small sample size or high variability
- **Example**: HR 0.65 (95% CI 0.62-0.68) very precise; HR 0.65 (0.30-1.40) imprecise
### Calculation Methods
**Hazard Ratio CI**
- From Cox regression output
- Standard error of log(HR) → exp(log(HR) ± 1.96×SE)
- Example: HR=0.62, SE(logHR)=0.185 → 95% CI (0.43, 0.89)
**Survival Rate CI (Greenwood Formula)**
- SE(S(t)) = S(t) × sqrt(Σ[d_i / (n_i × (n_i - d_i))])
- 95% CI: S(t) ± 1.96 × SE(S(t))
- Can use complementary log-log transformation for better properties
**Proportion CI (Exact Binomial)**
- For ORR, DCR: Use exact method (Clopper-Pearson) for small samples
- Wilson score interval: Better properties than normal approximation
- Example: 12/30 responses → ORR 40% (95% CI 22.7-59.4%)
## Censoring and Missing Data
### Types of Censoring
**Right Censoring**
- **End of study**: Patient alive at study termination (administrative censoring)
- **Loss to follow-up**: Patient stops attending visits
- **Withdrawal**: Patient withdraws consent
- **Competing risk**: Death from unrelated cause (in disease-specific survival)
**Handling Censoring**
- **Assumption**: Non-informative - censoring independent of event probability
- **Sensitivity Analysis**: Assess impact if assumption violated
- Best case: All censored patients never progress
- Worst case: All censored patients progress immediately after censoring
- Actual result should fall between best/worst case
### Missing Data
**Mechanisms**
- **MCAR (Missing Completely at Random)**: Missingness unrelated to any variable
- **MAR (Missing at Random)**: Missingness related to observed but not unobserved variables
- **NMAR (Not Missing at Random)**: Missingness related to the missing value itself
**Handling Strategies**
- **Complete case analysis**: Exclude patients with missing data (biased if not MCAR)
- **Multiple imputation**: Generate multiple plausible datasets, analyze each, pool results
- **Maximum likelihood**: Estimate parameters using all available data
- **Sensitivity analysis**: Assess robustness to missing data assumptions
**Response Assessment Missing Data**
- **Unevaluable for response**: Baseline measurable disease but post-baseline assessment missing
- Exclude from ORR denominator or count as non-responder (sensitivity analysis)
- **PFS censoring**: Last adequate tumor assessment date if later assessments missing
## Reporting Standards

# Patient Cohort Analysis Guide
## Overview
Patient cohort analysis involves systematically studying groups of patients to identify patterns, compare outcomes, and derive clinical insights. In pharmaceutical and clinical research settings, cohort analysis is essential for understanding treatment effectiveness, biomarker correlations, and patient stratification.
## Patient Stratification Methods

## Outcome Metrics
### Survival Endpoints
**Overall Survival (OS)**
- Definition: Time from treatment start (or randomization) to death from any cause
- Censoring: Last known alive date for patients lost to follow-up
- Reporting: Median OS, 1-year/2-year/5-year OS rates, hazard ratio
- Gold Standard: Primary endpoint for regulatory approval
**Progression-Free Survival (PFS)**
- Definition: Time from treatment start to disease progression or death
- Assessment: RECIST v1.1, iRECIST (for immunotherapy)
- Advantages: Earlier readout than OS, direct measure of treatment benefit
- Limitations: Requires imaging, subject to assessment timing
**Disease-Free Survival (DFS)**
- Definition: Time from complete response to recurrence or death (adjuvant setting)
- Application: Post-surgery, post-curative treatment
- Synonyms: Recurrence-free survival (RFS), event-free survival (EFS)
### Response Endpoints
**Objective Response Rate (ORR)**
- Definition: Proportion achieving complete response (CR) or partial response (PR)
- Measurement: RECIST v1.1 criteria (≥30% tumor shrinkage for PR)
- Reporting: ORR with 95% confidence interval
- Advantage: Earlier endpoint than survival
**Duration of Response (DOR)**
- Definition: Time from first response (CR/PR) to progression
- Population: Responders only
- Clinical Relevance: Durability of treatment benefit
- Reporting: Median DOR among responders
**Disease Control Rate (DCR)**
- Definition: CR + PR + stable disease (SD)
- Threshold: SD must persist ≥6-8 weeks typically
- Application: Less stringent than ORR, captures clinical benefit
### Quality of Life and Functional Status
**Performance Status**
- **ECOG Scale**: 0 (fully active) to 4 (bedridden)
- **Karnofsky Scale**: 100% (normal) to 0% (dead)
- **Assessment Frequency**: Baseline and each cycle
**Patient-Reported Outcomes (PROs)**
- **Symptom Scales**: EORTC QLQ-C30, FACT-G
- **Disease-Specific**: FACT-L (lung), FACT-B (breast)
- **Toxicity**: PRO-CTCAE for adverse events
- **Reporting**: Change from baseline, clinically meaningful differences
### Safety and Tolerability

- **Assumptions**: Expected count ≥5 in each cell
- **Reporting**: Proportions, chi-square statistic, df, p-value
**Fisher's Exact Test**
- **Application**: 2x2 tables with small sample sizes (expected count <5)
- **Advantage**: Exact p-value, no large-sample approximation
- **Limitation**: Computationally intensive for large tables
### Survival Analysis
**Kaplan-Meier Method**
- **Application**: Estimate survival curves with censored data
- **Output**: Survival probability at each time point, median survival
- **Visualization**: Step function curves with 95% CI bands
**Log-Rank Test**
- **Application**: Compare survival curves between groups
- **Null Hypothesis**: No difference in survival distributions
- **Reporting**: Chi-square statistic, df, p-value
- **Limitation**: Assumes proportional hazards
**Cox Proportional Hazards Model**
- **Application**: Multivariable survival analysis
- **Output**: Hazard ratio (HR) with 95% CI for each covariate
- **Interpretation**: HR > 1 (increased risk), HR < 1 (decreased risk)
- **Assumptions**: Proportional hazards (test with Schoenfeld residuals)
### Effect Sizes
**Hazard Ratio (HR)**
- Definition: Ratio of hazard rates between groups
- Interpretation: HR = 0.5 means 50% reduction in risk
- Reporting: HR (95% CI), p-value
- Example: HR = 0.65 (0.52-0.81), p<0.001
**Odds Ratio (OR)**
- Application: Case-control studies, logistic regression
- Interpretation: OR > 1 (increased odds), OR < 1 (decreased odds)
- Reporting: OR (95% CI), p-value
**Risk Ratio (RR) / Relative Risk**
- Application: Cohort studies, clinical trials
- Interpretation: RR = 2.0 means 2-fold increased risk
- More intuitive than OR for interpreting probabilities
### Multiple Testing Corrections
**Bonferroni Correction**
- Method: Divide α by number of tests (α/n)
- Example: 5 tests → significance threshold = 0.05/5 = 0.01
- Conservative: Reduces Type I error but increases Type II error
**False Discovery Rate (FDR)**
- Method: Benjamini-Hochberg procedure
- Interpretation: Expected proportion of false positives among significant results
- Less Conservative: More power than Bonferroni
**Family-Wise Error Rate (FWER)**
- Method: Control probability of any false positive
- Application: When even one false positive is problematic
- Examples: Bonferroni, Holm-Bonferroni
## Biomarker Correlation with Outcomes
### Predictive Biomarkers
**Definition**: Biomarkers that identify patients likely to respond to a specific treatment

- **HER2 3+**: Predicts response to trastuzumab (breast cancer)
- **EGFR mutations**: Predicts response to EGFR TKIs (lung cancer)
- **BRAF V600E**: Predicts response to vemurafenib (melanoma)
- **MSI-H/dMMR**: Predicts response to immune checkpoint inhibitors
**Analysis**
- Stratified analysis: Compare treatment effect within biomarker-positive vs negative
- Interaction test: Test if treatment effect differs by biomarker status
- Reporting: HR in biomarker+ vs biomarker-, interaction p-value
### Prognostic Biomarkers
**Definition**: Biomarkers that predict outcome regardless of treatment
**Examples**
- **High Ki-67**: Poor prognosis independent of treatment (breast cancer)
- **TP53 mutation**: Poor prognosis in many cancers
- **Low albumin**: Poor prognosis marker (many diseases)
- **Elevated LDH**: Poor prognosis (melanoma, lymphoma)
**Analysis**
- Compare outcomes across biomarker levels in untreated or uniformly treated cohort
- Multivariable Cox model adjusting for other prognostic factors
- Validate in independent cohorts
### Continuous Biomarker Analysis
**Cut-Point Selection**
- **Data-Driven**: Maximally selected rank statistics, ROC curve analysis
- **Literature-Based**: Established clinical cut-points
- **Median/Tertiles**: Simple divisions for exploration
- **Validation**: Cut-points must be validated in independent cohort
**Continuous Analysis**
- Treat biomarker as continuous variable in Cox model
- Report HR per unit increase or per standard deviation
- Spline curves to assess non-linear relationships
- Advantage: No information loss from dichotomization

- **Consistency**: Cross-field validation, logical checks
- **Outliers**: Identify and investigate extreme values
- **Duplicates**: Patient ID verification, enrollment checks
### Statistical Assumptions
- **Normality**: Shapiro-Wilk test, Q-Q plots for continuous variables
- **Proportional Hazards**: Schoenfeld residuals for Cox models
- **Independence**: Check for clustering, matched data
- **Missing Data**: Assess mechanism (MCAR, MAR, NMAR), handle appropriately
### Reporting Standards
- **CONSORT**: Randomized controlled trials
- **STROBE**: Observational studies
- **REMARK**: Tumor marker prognostic studies
- **STARD**: Diagnostic accuracy studies
- **TRIPOD**: Prediction model development/validation
## Clinical Interpretation
### Translating Statistics to Clinical Meaning
**Statistical Significance vs Clinical Significance**
- p<0.05 does not guarantee clinical importance
- Small effects can be statistically significant with large samples
- Large effects can be non-significant with small samples
- Consider effect size magnitude and confidence interval width
**Number Needed to Treat (NNT)**
- NNT = 1 / absolute risk reduction
- Example: 10% vs 5% event rate → ARR = 5% → NNT = 20
- Interpretation: Treat 20 patients to prevent 1 event
- Useful for communicating treatment benefit
**Minimal Clinically Important Difference (MCID)**
- Pre-defined threshold for meaningful clinical benefit
- OS: Often 2-3 months in oncology
- PFS: Context-dependent, often 1.5-3 months
- QoL: 10-point change on 100-point scale
- Response rate: Often 10-15 percentage point difference
### Contextualization
- Compare to historical controls or standard of care
- Consider patient population characteristics
- Account for prior treatment exposure
- Evaluate toxicity trade-offs
- Assess quality of life impact

# Treatment Recommendations Guide
## Overview
Evidence-based treatment recommendations provide clinicians with systematic guidance for therapeutic decision-making. This guide covers the development, grading, and presentation of clinical recommendations in pharmaceutical and healthcare settings.
## Evidence Grading Systems
### GRADE (Grading of Recommendations Assessment, Development and Evaluation)
**Quality of Evidence Levels**
**High Quality (⊕⊕⊕⊕)**
- Further research very unlikely to change confidence in estimate
- Criteria: Well-designed RCTs with consistent results, no serious limitations
- Example: Multiple large RCTs showing similar treatment effects
**Moderate Quality (⊕⊕⊕○)**
- Further research likely to have important impact on confidence
- Criteria: RCTs with limitations OR very strong evidence from observational studies
- Example: Single RCT or multiple RCTs with some inconsistency
**Low Quality (⊕⊕○○)**
- Further research very likely to have important impact on confidence
- Criteria: Observational studies OR RCTs with serious limitations
- Example: Case-control studies, cohort studies with confounding
**Very Low Quality (⊕○○○)**
- Estimate of effect very uncertain
- Criteria: Case series, expert opinion, or very serious limitations
- Example: Mechanistic reasoning, unsystematic clinical observations
**Strength of Recommendation**
**Strong Recommendation (Grade 1)**
- Benefits clearly outweigh risks and burdens (or vice versa)
- Wording: "We recommend..."
- Implications: Most patients should receive recommended course
- Symbol: ↑↑ (strong for) or ↓↓ (strong against)
**Conditional/Weak Recommendation (Grade 2)**
- Trade-offs exist; benefits and risks closely balanced
- Wording: "We suggest..."
- Implications: Different choices for different patients; shared decision-making
- Symbol: ↑ (weak for) or ↓ (weak against)
**GRADE Notation Examples**
- **1A**: Strong recommendation, high-quality evidence
- **1B**: Strong recommendation, moderate-quality evidence
- **2A**: Weak recommendation, high-quality evidence
- **2B**: Weak recommendation, moderate-quality evidence
- **2C**: Weak recommendation, low- or very low-quality evidence
### Oxford Centre for Evidence-Based Medicine (CEBM) Levels
**Level 1: Systematic Review/Meta-Analysis**
- 1a: SR of RCTs
- 1b: Individual RCT with narrow confidence interval
- 1c: All-or-none studies (all patients died before treatment, some survive after)
**Level 2: Cohort Studies**
- 2a: SR of cohort studies
- 2b: Individual cohort study (including low-quality RCT)
- 2c: Outcomes research, ecological studies
**Level 3: Case-Control Studies**
- 3a: SR of case-control studies
- 3b: Individual case-control study
**Level 4: Case Series**
- Case series, poor-quality cohort, or case-control studies
**Level 5: Expert Opinion**
- Mechanism-based reasoning, expert opinion without critical appraisal
**Grades of Recommendation**
- **Grade A**: Consistent level 1 studies
- **Grade B**: Consistent level 2 or 3 studies, or extrapolations from level 1
- **Grade C**: Level 4 studies or extrapolations from level 2 or 3
- **Grade D**: Level 5 evidence or inconsistent/inconclusive studies
## Treatment Sequencing and Line-of-Therapy
### First-Line Therapy
**Selection Criteria**
- **Standard of Care**: Guideline-recommended based on phase 3 trials
- **Patient Factors**: Performance status, comorbidities, organ function
- **Disease Factors**: Stage, molecular profile, aggressiveness
- **Goals**: Cure (adjuvant/neoadjuvant), prolonged remission, symptom control
**First-Line Options Documentation**
```
First-Line Treatment Options:
Option 1: Regimen A (NCCN Category 1, ESMO I-A)
- Evidence: Phase 3 RCT (n=1000), median PFS 12 months vs 8 months (HR 0.6, p<0.001)
- Population: PD-L1 ≥50%, EGFR/ALK negative
- Toxicity Profile: Immune-related AEs (15% grade 3-4)
- Recommendation Strength: 1A (strong, high-quality evidence)
Option 2: Regimen B (NCCN Category 1, ESMO I-A)
- Evidence: Phase 3 RCT (n=800), median PFS 10 months vs 8 months (HR 0.7, p=0.003)
- Population: All patients, no biomarker selection
- Toxicity Profile: Hematologic toxicity (25% grade 3-4)
- Recommendation Strength: 1A (strong, high-quality evidence)
```
### Second-Line and Beyond
**Second-Line Selection**
- **Prior Response**: Duration of response to first-line
- **Progression Pattern**: Oligoprogression vs widespread progression
- **Residual Toxicity**: Recovery from first-line toxicities
- **Biomarker Evolution**: Acquired resistance mechanisms
- **Clinical Trial Availability**: Novel agents in development
**Treatment History Documentation**
```
Prior Therapies:
1. First-Line: Pembrolizumab (12 cycles)
- Best Response: Partial response (-45% tumor burden)
- PFS: 14 months
- Discontinuation Reason: Progressive disease
- Residual Toxicity: Grade 1 hypothyroidism (on levothyroxine)
2. Second-Line: Docetaxel + ramucirumab (6 cycles)
- Best Response: Stable disease
- PFS: 5 months
- Discontinuation Reason: Progressive disease
- Residual Toxicity: Grade 2 peripheral neuropathy
Current Consideration: Third-Line Options
- Clinical trial vs platinum-based chemotherapy
```
### Maintenance Therapy
**Indications**
- Consolidation after response to induction therapy
- Prevention of progression without continuous cytotoxic treatment
- Bridging to definitive therapy (e.g., transplant)
**Evidence Requirements**
- PFS benefit demonstrated in randomized trials
- Tolerable long-term toxicity profile
- Quality of life preserved or improved
## Biomarker-Guided Therapy Selection
### Companion Diagnostics
**FDA-Approved Biomarker-Drug Pairs**
**Required Testing (Treatment-Specific)**
- **ALK rearrangement → Alectinib, Brigatinib, Lorlatinib** (NSCLC)
- **EGFR exon 19 del/L858R → Osimertinib** (NSCLC)
- **BRAF V600E → Dabrafenib + Trametinib** (Melanoma, NSCLC, CRC)
- **HER2 amplification/3+ → Trastuzumab, Pertuzumab** (Breast, Gastric)
- **PD-L1 ≥50% → Pembrolizumab monotherapy** (NSCLC first-line)
**Complementary Diagnostics (Informative but not Required)**
- **PD-L1 1-49%**: Combination immunotherapy preferred
- **TMB-high**: May predict immunotherapy benefit (investigational)
- **MSI-H/dMMR**: Pembrolizumab approved across tumor types
### Biomarker Testing Algorithms
**NSCLC Biomarker Panel**
```
Reflex Testing at Diagnosis:
✓ EGFR mutations (exons 18, 19, 20, 21)
✓ ALK rearrangement (IHC or FISH)
✓ ROS1 rearrangement (FISH or NGS)
✓ BRAF V600E mutation
✓ PD-L1 IHC (22C3 or SP263)
✓ Consider: Comprehensive NGS panel
If EGFR+ on Osimertinib progression:
✓ Liquid biopsy for T790M (if first/second-gen TKI)
✓ Tissue biopsy for resistance mechanisms
✓ MET amplification, HER2 amplification, SCLC transformation
```
**Breast Cancer Biomarker Algorithm**
```
Initial Diagnosis:
✓ ER/PR IHC
✓ HER2 IHC and FISH (if 2+)
✓ Ki-67 proliferation index
If Metastatic ER+/HER2-:
✓ ESR1 mutations (liquid biopsy after progression on AI)
✓ PIK3CA mutations (for alpelisib eligibility)
✓ BRCA1/2 germline testing (for PARP inhibitor eligibility)
✓ PD-L1 testing (if considering immunotherapy combinations)
```
### Actionable Alterations
**Tier I: FDA-Approved Targeted Therapy**
- Strong evidence from prospective trials
- Guideline-recommended
- Examples: EGFR exon 19 deletion, HER2 amplification, ALK fusion
**Tier II: Clinical Trial or Off-Label Use**
- Emerging evidence, clinical trial preferred
- Examples: NTRK fusion (larotrectinib), RET fusion (selpercatinib)
**Tier III: Biological Plausibility**
- Preclinical evidence only
- Clinical trial enrollment strongly recommended
- Examples: Novel kinase fusions, rare resistance mutations
## Combination Therapy Protocols
### Rationale for Combinations
**Mechanisms**
- **Non-Overlapping Toxicity**: Maximize dose intensity of each agent
- **Synergistic Activity**: Enhanced efficacy beyond additive effects
- **Complementary Mechanisms**: Target multiple pathways simultaneously
- **Prevent Resistance**: Decrease selection pressure for resistant clones
**Combination Design Principles**
- **Sequential**: Induction then consolidation (different regimens)
- **Concurrent**: Administered together for synergy
- **Alternating**: Rotate regimens to minimize resistance
- **Intermittent**: Pulse dosing vs continuous exposure
### Drug Interaction Assessment
**Pharmacokinetic Interactions**
- **CYP450 Induction/Inhibition**: Check for drug-drug interactions
- **Transporter Interactions**: P-gp, BCRP, OATP substrates/inhibitors
- **Protein Binding**: Highly protein-bound drugs (warfarin caution)
- **Renal/Hepatic Clearance**: Avoid multiple renally cleared agents
**Pharmacodynamic Interactions**
- **Additive Toxicity**: Avoid overlapping adverse events (e.g., QTc prolongation)
- **Antagonism**: Ensure mechanisms are complementary, not opposing
- **Dose Modifications**: Pre-defined dose reduction schedules for combinations
### Combination Documentation
```
Combination Regimen: Drug A + Drug B
Rationale:
- Phase 3 RCT demonstrated PFS benefit (16 vs 11 months, HR 0.62, p<0.001)
- Complementary mechanisms: Drug A (VEGF inhibitor) + Drug B (immune checkpoint inhibitor)
- Non-overlapping toxicity profiles
Dosing:
- Drug A: 10 mg/kg IV every 3 weeks
- Drug B: 1200 mg IV every 3 weeks
- Continue until progression or unacceptable toxicity
Key Toxicities:
- Hypertension (Drug A): 30% grade 3-4, manage with antihypertensives
- Immune-related AEs (Drug B): 15% grade 3-4, corticosteroid management
- No significant pharmacokinetic interactions observed
Monitoring:
- Blood pressure: Daily for first month, then weekly
- Thyroid function: Every 6 weeks
- Liver enzymes: Before each cycle
- Imaging: Every 6 weeks (RECIST v1.1)
```
## Monitoring and Follow-up Schedules
### On-Treatment Monitoring
**Laboratory Monitoring**
```
Test Baseline Cycle 1 Cycle 2+ Rationale
CBC with differential ✓ Weekly Day 1 Myelosuppression risk
Comprehensive panel ✓ Day 1 Day 1 Electrolytes, renal, hepatic
Thyroid function ✓ - Q6 weeks Immunotherapy
Lipase/amylase ✓ - As needed Pancreatitis risk
Troponin/BNP ✓* - As needed Cardiotoxicity risk
(*if cardiotoxic agent)
```
**Imaging Assessment**
```
Modality Baseline Follow-up Criteria
CT chest/abd/pelvis ✓ Every 6-9 weeks RECIST v1.1
Brain MRI ✓* Every 12 weeks If CNS metastases
Bone scan ✓** Every 12-24 weeks If bone metastases
PET/CT ✓*** Response assessment Lymphoma (Lugano criteria)
(*if CNS mets, **if bone mets, ***if PET-avid tumor)
```
**Clinical Assessment**
```
Assessment Frequency Notes
ECOG performance status Every visit Decline may warrant dose modification
Vital signs Every visit Blood pressure for anti-VEGF agents
Weight Every visit Cachexia, fluid retention
Symptom assessment Every visit PRO-CTCAE questionnaire
Physical exam Every visit Target lesions, new symptoms
```
### Dose Modification Guidelines
**Hematologic Toxicity**
```
ANC and Platelet Counts Action
ANC ≥1.5 AND platelets ≥100k Treat at full dose
ANC 1.0-1.5 OR platelets 75-100k Delay 1 week, recheck
ANC 0.5-1.0 OR platelets 50-75k Delay treatment, G-CSF support, reduce dose 20%
ANC <0.5 OR platelets <50k Hold treatment, G-CSF, transfusion PRN, reduce 40%
Febrile Neutropenia Hold treatment, hospitalize, antibiotics, G-CSF
Reduce dose 20-40% on recovery, consider prophylactic G-CSF
```
**Non-Hematologic Toxicity**
```
Adverse Event Grade 1 Grade 2 Grade 3 Grade 4
Diarrhea Continue Continue with Hold until ≤G1, Hold, hospitalize
loperamide reduce 20% Consider discontinuation
Rash Continue Continue with Hold until ≤G1, Discontinue
topical Rx reduce 20%
Hepatotoxicity Continue Repeat in 1 wk, Hold until ≤G1, Discontinue permanently
hold if worsening reduce 20-40%
Pneumonitis Continue Hold, consider Hold, corticosteroids, Discontinue, high-dose
corticosteroids discontinue if no improvement steroids
```
### Post-Treatment Surveillance
**Disease Monitoring**
```
Time After Treatment Imaging Frequency Labs Clinical
Year 1 Every 3 months Every 3 months Every 3 months
Year 2 Every 3-4 months Every 3-4 months Every 3-4 months
Years 3-5 Every 6 months Every 6 months Every 6 months
Year 5+ Annually Annually Annually
Earlier imaging if symptoms suggest recurrence
```
**Survivorship Care**
```
Surveillance Frequency Duration
Disease monitoring Per schedule above Lifelong or until recurrence
Late toxicity screening Annually Lifelong
- Cardiac function Every 1-2 years If anthracycline/trastuzumab
- Pulmonary function As clinically indicated If bleomycin/radiation
- Neuropathy Symptom-based Peripheral neuropathy history
- Secondary malignancy Age-appropriate screening Lifelong (increased risk)
Genetic counseling One time If hereditary cancer syndrome
Psychosocial support As needed Depression, anxiety, PTSD screening
```
## Special Populations
### Elderly Patients (≥65-70 years)
**Considerations**
- **Reduced organ function**: Adjust for renal/hepatic impairment
- **Polypharmacy**: Drug-drug interaction risk
- **Frailty**: Geriatric assessment (G8, VES-13, CARG score)
- **Goals of care**: Quality of life vs survival, functional independence
**Modifications**
- Dose reductions: 20-25% reduction for frail patients
- Longer intervals: Every 4 weeks instead of every 3 weeks
- Less aggressive regimens: Single-agent vs combination therapy
- Supportive care: Increased monitoring, G-CSF prophylaxis
### Renal Impairment
**Dose Adjustments by eGFR**
```
eGFR (mL/min/1.73m²) Category Action
≥90 Normal Standard dosing
60-89 Mild Standard dosing (most agents)
30-59 Moderate Dose reduce renally cleared drugs 25-50%
15-29 Severe Dose reduce 50-75%, avoid nephrotoxic agents
<15 (dialysis) ESRD Avoid most agents, case-by-case decisions
```
**Renally Cleared Agents Requiring Adjustment**
- Carboplatin (Calvert formula: AUC × [GFR + 25])
- Methotrexate (reduce dose 50-75% if CrCl <60)
- Capecitabine (reduce dose 25-50% if CrCl 30-50)
### Hepatic Impairment
**Dose Adjustments by Bili and AST/ALT**
```
Category Bilirubin AST/ALT Action
Normal ≤ULN ≤ULN Standard dosing
Mild (Child A) 1-1.5× ULN Any Reduce dose 25% for hepatically metabolized
Moderate (Child B) 1.5-3× ULN Any Reduce dose 50%, consider alternative
Severe (Child C) >3× ULN Any Avoid most agents, case-by-case
```
**Hepatically Metabolized Agents Requiring Adjustment**
- Docetaxel (reduce 25-50% if bilirubin elevated)
- Irinotecan (reduce 50% if bilirubin 1.5-3× ULN)
- Tyrosine kinase inhibitors (most metabolized by CYP3A4, reduce by 50%)
### Pregnancy and Fertility
**Contraception Requirements**
- Effective contraception required during treatment and 6-12 months after
- Two methods recommended for highly teratogenic agents
- Male patients: Contraception if partner of childbearing potential
**Fertility Preservation**
- Oocyte/embryo cryopreservation (females, before gonadotoxic therapy)
- Sperm banking (males, before alkylating agents, platinum)
- GnRH agonists (ovarian suppression, controversial efficacy)
- Referral to reproductive endocrinology before treatment
**Pregnancy Management**
- Avoid chemotherapy in first trimester (organogenesis)
- Selective agents safe in second/third trimester (case-by-case)
- Multidisciplinary team: oncology, maternal-fetal medicine, neonatology
## Clinical Trial Considerations
### When to Recommend Clinical Trials
**Ideal Scenarios**
- No standard therapy available (rare diseases, refractory settings)
- Multiple equivalent standard options (patient preference for novel agent)
- Standard therapy failed (second-line and beyond)
- High-risk disease (adjuvant trials for improved outcomes)
**Trial Selection Criteria**
- **Phase**: Phase 1 (dose-finding, safety), Phase 2 (efficacy signal), Phase 3 (comparative effectiveness)
- **Eligibility**: Match patient to inclusion/exclusion criteria
- **Mechanism**: Novel vs established mechanism, biological rationale
- **Sponsor**: Academic vs industry, trial design quality
- **Logistics**: Distance to trial site, visit frequency, out-of-pocket costs
### Shared Decision-Making
**Informing Patients**
- Natural history without treatment
- Standard treatment options with evidence, benefits, risks
- Clinical trial options (if available)
- Goals of care alignment
- Patient values and preferences
**Decision Aids**
- Visual representations of benefit (icon arrays)
- Number needed to treat calculations
- Quality of life trade-offs
- Decisional conflict scales

- Ensure no reflection or background identification
- [ ] **18. Any other unique identifying characteristic or code**
- No unique characteristics that could identify individual
- No rare disease combinations that could identify
- Consider if combination of remaining data points could identify individual
---
## Additional De-identification Considerations
### Ages and Dates
- [ ] Patients aged ≤89: Exact age or age range acceptable
- [ ] Patients aged >89: Must be aggregated to "90 or older" or ">89 years"
- [ ] Dates: Use only years OR use relative time periods
- Example: "3 months prior to presentation" instead of "on January 15, 2023"
- Example: "admitted in 2023" instead of "admitted on March 10, 2023"
### Geographic Information
- [ ] State or country is acceptable
- [ ] Removed specific cities (unless population >20,000 and no other identifying information)
- [ ] Removed hospital/clinic names
- [ ] Use general descriptors: "a community hospital in the Midwest" or "a tertiary care center"
### Rare Conditions and Combinations
- [ ] Consider if very rare disease alone could identify patient
- [ ] Consider if combination of:
- Age + diagnosis + geographic area + timeframe could identify patient
- [ ] May need to be vague about certain unique details
- [ ] Balance between providing clinical information and protecting privacy
### Images and Figures
- [ ] All patient identifiers removed from image headers/metadata
- [ ] DICOM data stripped
- [ ] Dates removed from images
- [ ] Medical record numbers removed
- [ ] Faces cropped, blurred, or obscured
- [ ] Identifying marks removed or obscured:
- Tattoos
- Jewelry
- Birthmarks or unique scars (if not clinically relevant)
- [ ] Scale bars and annotations do not contain identifying information
- [ ] Background environment de-identified (room numbers, nameplates, etc.)
### Voice and Video
- [ ] No audio recordings with patient voice (unless consent obtained)
- [ ] No video showing identifiable features (unless consent obtained)
- [ ] If video necessary, face must be obscured
---
## Informed Consent Checklist (for Case Reports/Publications)
### Consent Requirements
- [ ] Informed consent obtained BEFORE publication submission
- [ ] Consent obtained from patient directly (if capable)
- [ ] If patient deceased or incapacitated, consent from legal representative or next of kin

The informed consent form must include:
- [ ] Purpose of publication (education, medical knowledge)
- [ ] What will be published (case details, images, outcomes)
- [ ] Journal or publication venue (if known)
- [ ] Open access vs. subscription (public availability)
- [ ] De-identification efforts explained
- [ ] Potential for re-identification acknowledged
- [ ] No effect on clinical care
- [ ] Right to withdraw consent (timing limitations)
- [ ] Contact information for questions
- [ ] Patient signature and date
- [ ] Witness signature (if required)
### Consent Documentation
- [ ] Signed consent form on file
- [ ] Copy provided to patient
- [ ] Consent available for editor review
- [ ] Statement in manuscript confirming consent obtained
**Example statement for manuscript:**
"Written informed consent was obtained from the patient for publication of this case report and any accompanying images. A copy of the written consent is available for review by the Editor-in-Chief of this journal on request."

## Template Notes
### General Principles
**Be systematic:**
- Use consistent order (head to toe, outside to inside)
- Don't skip regions even if normal
- Include pertinent negatives
**Be specific:**
- Provide measurements (size in 3 dimensions for masses)
- Describe location precisely
- Use standardized terminology (RadLex)
- Quantify when possible
**Be clear:**
- Avoid ambiguous language
- Make impression stand-alone
- Answer the clinical question directly
- State what IS present, not just what isn't
**Communication:**
- Critical findings require immediate verbal notification
- Document communication
- Provide specific recommendations
- Suggest next steps when appropriate
### Measurement Guidelines
**Lesions/Masses:**
- Three dimensions: [length x width x height in cm]
- Use consistent measurement method for follow-up
**Lymph Nodes:**
- Short axis diameter in cm
- Note morphology (round vs. oval)
**Organ Sizes:**
- Use established normal ranges
- Age and sex appropriate
### Comparison Statements
**Improved:**
"Interval decrease in size of right upper lobe mass from 3.5 cm to 2.1 cm."
**Stable:**
"Unchanged 8 mm left lower lobe nodule, stable for 2 years."
**Worsened:**
"Interval increase in bilateral pleural effusions, now moderate on the right."
**New finding:**
"New 1.5 cm right adrenal nodule, not present on prior CT."
### Differential Diagnosis Language
**Definite:** "Consistent with..."
**Probable:** "Most likely represents..." or "Favors..."
**Possible:** "Suggestive of..." or "Differential diagnosis includes..."
**Uncertain:** "Cannot exclude..." or "Consider..."
### Recommendations
**Follow-up imaging:**
- Specify modality, timing, and what to assess
- "Recommend CT chest in 6-12 months to assess stability"
**Further characterization:**
- "Consider MRI for further characterization"
- "Ultrasound correlation recommended"
**Clinical correlation:**
- "Clinical correlation with tumor markers recommended"
- "Correlate with patient symptoms and physical examination"
**Biopsy/Intervention:**
- "Consider biopsy for definitive diagnosis"
- "Amenable to image-guided biopsy if clinically indicated"

### 18 HIPAA Identifiers to Remove
Complete list of protected health information (PHI) that must be removed for Safe Harbor de-identification:
1. **Names** - Patient name, family members' names, healthcare provider names
2. **Geographic subdivisions smaller than state** - Street addresses, cities, counties, ZIP codes (can keep first 3 digits if >20,000 people in area)
3. **Dates** - Exact dates of birth, admission, discharge, death (keep year or use intervals)
4. **Telephone numbers** - Any phone numbers related to patient
5. **Fax numbers**
6. **Email addresses**
7. **Social Security numbers**
8. **Medical record numbers**
9. **Health plan beneficiary numbers**
10. **Account numbers**
11. **Certificate/license numbers**
12. **Vehicle identifiers** - License plates, VINs
13. **Device identifiers and serial numbers** - Pacemakers, implants (unless generic)
14. **Web URLs**
15. **IP addresses**
16. **Biometric identifiers** - Fingerprints, voice prints, retinal scans
17. **Full-face photographs** - Must obscure or obtain consent
18. **Any other unique identifying characteristic or code**
### De-identification Best Practices
**Age Reporting:**
- For adults: Can use exact age or age ranges (e.g., "a woman in her 50s")
- For patients >89 years: Must aggregate (e.g., "a woman in her 90s" or ">89 years")
- For pediatric cases: Use months for infants, years for children
**Date Reporting:**
- Use relative time intervals instead of exact dates
- Example: "Three months prior to presentation..." instead of "On January 15, 2023..."
- Can keep year if needed for context
- Use "Day 0, Day 1, Day 2" for timelines
**Location:**
- State or country acceptable
- Remove city, hospital name, specific clinic
- Example: "A community hospital in the Midwest" or "A tertiary care center in California"
**Rare Conditions:**
- Very rare conditions may themselves be identifying
- Consider whether the combination of diagnosis, location, and timeframe could identify patient
- May need to be vague about certain details
**Images:**
- Crop or blur faces
- Remove jewelry, tattoos, or identifying marks
- Crop images to show only relevant clinical findings
- Consider using illustrations instead of photographs
- Black bars over eyes are NOT sufficient
- Get explicit consent for recognizable images
**Pathology and Imaging:**
- Remove patient identifiers from image headers
- Remove dates from images
- Remove medical record numbers from labels
## Writing Style and Language
### Clarity and Precision
**Use clear, specific language:**
- Good: "The patient's hemoglobin decreased from 12.5 g/dL to 7.2 g/dL over 48 hours"
- Poor: "The patient's blood count dropped significantly"
**Avoid ambiguous terms:**
- Instead of "several," specify the number
- Instead of "recently," give timeframe
- Instead of "significant," provide exact values and p-values if applicable
**Use active voice when appropriate:**
- Good: "We diagnosed the patient with acute appendicitis"
- Acceptable: "The patient was diagnosed with acute appendicitis"
### Professional Tone
- Objective and factual
- Avoid sensationalism
- Respectful toward patient and healthcare team
- Avoid value judgments
- Focus on clinical facts and medical reasoning
### Tense
- **Abstract**: Usually past tense
- **Introduction**: Present tense for background, past tense for case description
- **Case presentation**: Past tense
- **Discussion**: Present tense for established knowledge, past tense for this case
### Common Mistakes to Avoid
1. **Insufficient novelty** - Reporting common presentations without unique aspects
2. **Missing informed consent** - Failing to obtain or document consent
3. **Inadequate de-identification** - Leaving identifiable information
4. **Poor literature review** - Not contextualizing within existing knowledge
5. **Excessive length** - Including unnecessary details
6. **Lack of structure** - Not following CARE guidelines or journal format
7. **Overgeneralization** - Drawing broad conclusions from one case
8. **Missing timeline** - Not providing clear chronology
9. **Vague outcomes** - Not clearly describing clinical outcome
10. **No learning points** - Failing to articulate clinical lessons
## Learning Points Format
Many journals require a "Learning Points" or "Key Messages" section with 3-5 bulleted takeaways.
**Characteristics of good learning points:**
- Concise (1-2 sentences each)
- Clinically actionable
- Generalizable beyond this specific case
- Focus on diagnosis, treatment, or recognition
- Avoid overgeneralization
**Example:**
- "Aortic dissection can present with atypical symptoms that mimic pneumonia, including cough and dyspnea without chest pain."
- "Blood pressure differential between arms >20 mmHg should raise suspicion for aortic dissection."
- "CT angiography is the gold standard for diagnosing acute aortic dissection and should be performed urgently in high-risk patients."
## Literature Search Strategies
**Databases to search:**
- PubMed/MEDLINE
- Embase
- Google Scholar
- Scopus
- Web of Science
**Search terms:**
- Disease or condition name
- Key clinical features
- Treatment or intervention
- Use MeSH terms
- Combine with "case report" or "case series"
**When citing literature:**
- Cite most relevant and recent cases
- Include systematic reviews if available
- Cite original descriptions of rare conditions
- Balance supporting and contrasting evidence
- Typically 15-30 references for case report

A 58-year-old male (Subject ID: 12345) enrolled in Study XYZ-301, a Phase 3
randomized trial of Drug X vs. placebo for heart failure. On Day 42 of treatment
(15-Feb-2024), the patient presented to the emergency department with sudden onset
severe chest pain, diaphoresis, and dyspnea. ECG showed ST-segment elevation in
leads V2-V4. Troponin I was elevated at 12.5 ng/mL (normal <0.04). The patient was
diagnosed with acute ST-elevation myocardial infarction and underwent emergent
cardiac catheterization revealing 95% occlusion of the left anterior descending
artery. Percutaneous coronary intervention with drug-eluting stent placement was
performed successfully. The patient was admitted to the cardiac intensive care unit.
Study drug was permanently discontinued on Day 42. The patient recovered and was
discharged on Day 47 (20-Feb-2024) in stable condition. This event was assessed as
unlikely related to study drug by the investigator, as the patient had significant
underlying coronary artery disease risk factors including diabetes, hypertension,
and smoking history.
```
### Regulatory Reporting Timelines
**FDA IND Safety Reporting (21 CFR 312.32):**
- **Fatal or life-threatening unexpected SAEs**: 7 calendar days for preliminary report, 15 days for complete report
- **Other serious unexpected events**: 15 calendar days
- **Annual safety reports**: Within 60 days of anniversary of IND
**EMA Expedited Reporting:**
- **Fatal or life-threatening unexpected events**: 7 days initial, 8 additional days for complete report
- **Other unexpected serious events**: 15 days
**IRB Reporting:**
- Per institutional policy
- Typically 5-10 days for serious unexpected events
- Some institutions require reporting within 24-48 hours
### MedDRA Coding
**MedDRA (Medical Dictionary for Regulatory Activities):**
- Standardized medical terminology for regulatory communication
- Hierarchical structure:
- SOC (System Organ Class) - highest level
- HLGT (High Level Group Term)
- HLT (High Level Term)
- PT (Preferred Term) - used for coding AEs
- LLT (Lowest Level Term) - verbatim terms
**Example:**
- Verbatim term: "bad headache"
- LLT: Headache
- PT: Headache
- HLT: Headaches NEC
- HLGT: Neurological disorders NEC
- SOC: Nervous system disorders
### Causality Assessment Methods
**WHO-UMC Causality Categories:**
- **Certain**: Event cannot be explained by other factors

- Overlay normal distribution curve (if testing normality)
## Special Considerations for Clinical Data
### Presenting Proportions
**Numerator and denominator:**
- Always provide both: 25/100 (25%)
- Not just percentage (25%)
**Percentages:**
- No decimal places if n<100
- 1 decimal place if n≥100
- Never report >1 decimal place for percentages
**Confidence intervals for proportions:**
- Wilson score interval or exact binomial (better than Wald for small samples)
- Always report with percentage
### Presenting Continuous Data
**Measures of central tendency:**
- Mean for normally distributed data
- Median for skewed data or ordinal data
- Report both if distribution unclear
**Measures of dispersion:**
- **Standard deviation (SD)**: Describes variability in data
- **Standard error (SE)**: Describes precision of mean estimate
- **95% Confidence interval**: Preferred for inferential statistics
- **Interquartile range (IQR)**: With median for skewed data
- **Range**: Min to max
**When to use each:**
- Descriptive statistics → Mean (SD) or Median (IQR)
- Inferential statistics → Mean (95% CI) or Mean (SE)
- Never use ± without specifying SD, SE, or CI
### Presenting P-values
**Reporting guidelines:**
- Report exact p-values to 2-3 decimal places (p=0.042)
- For very small p-values, use p<0.001 (not p=0.000)
- Do not report as "NS" or "p=NS"
- For non-significant results, report exact p-value (p=0.18, not p>0.05)
- Specify two-tailed unless pre-specified one-tailed
- Correct for multiple comparisons when appropriate
- Report significance threshold used (α=0.05 is standard)
**Avoid:**
- p<0.05 (report exact value)
- p=0.00 (impossible)
- Multiple decimal places (p=0.04235891)
### Statistical Significance Indicators
**Options:**
1. Report p-values in table
2. Use asterisks with legend:
- *p<0.05
- **p<0.01
- ***p<0.001
3. Use confidence intervals (preferred)
### Confidence Intervals
**Reporting:**
- 95% CI is standard
- Format: (lower limit, upper limit)
- Or: lower limit to upper limit
- Or: lower limit-upper limit
**Interpretation:**
- If CI for difference excludes 0 → significant
- If CI for ratio excludes 1 → significant
- Width of CI indicates precision
### Missing Data
**Indicate clearly:**
- Footnote explaining missing data
- State clearly if analysis is complete case
- Describe imputation method if used
- Report amount of missing data per variable
### Decimal Places and Rounding
**General rules:**
- Report to level of measurement precision
- Consistent decimal places within table
- Round p-values to 2-3 decimal places
- Round percentages to 0-1 decimal place
- Round means/medians to 1-2 decimal places
- Include appropriate significant figures
## Software for Creating Figures
**Statistical software:**
- R (ggplot2) - highly customizable

- Python (matplotlib, seaborn) - flexible and powerful
**General graphics software:**
- Adobe Illustrator - professional publication-quality
- Inkscape - free vector graphics editor
- PowerPoint - basic graphs, easy to use
- BioRender - biological schematics and figures
## Color Schemes
**Color-blind friendly palettes:**
- Avoid red-green combinations
- Use blue-orange, blue-yellow
- Include shape/pattern differences
- Test figures in grayscale
**Recommended palettes:**
- ColorBrewer (designed for data visualization)
- Viridis (perceptually uniform)
- IBM Color Blind Safe Palette
## Image Quality Standards
**Resolution:**
- 300 dpi for print publication
- 150 dpi for web/screen
- Vector graphics (PDF, SVG) preferred for graphs
**File formats:**
- TIFF or EPS for print
- PNG for web
- PDF for vector graphics

# DOCX creation, editing, and analysis
## Overview
A .docx file is a ZIP archive containing XML files and resources. Create, edit, or analyze Word documents using text extraction, raw XML access, or redlining workflows. Apply this skill for professional document processing, tracked changes, and content manipulation.
## Visual Enhancement with Scientific Schematics
**When creating documents with this skill, always consider adding scientific diagrams and schematics to enhance visual communication.**
If your document does not already contain schematics or diagrams:
- Use the **scientific-schematics** skill to generate AI-powered publication-quality diagrams
- Simply describe your desired diagram in natural language
- Nano Banana Pro will automatically generate, review, and refine the schematic
**For new documents:** Scientific schematics should be generated by default to visually represent key concepts, workflows, architectures, or relationships described in the text.
**How to generate schematics:**
```bash
python scripts/generate_schematic.py "your diagram description" -o figures/output.png
```
The AI will automatically:
- Create publication-quality images with proper formatting
- Review and refine through multiple iterations
- Ensure accessibility (colorblind-friendly, high contrast)
- Save outputs in the figures/ directory
**When to add schematics:**
- Document workflow diagrams
- Process flowcharts
- System architecture illustrations
- Data flow diagrams
- Organizational structure diagrams
- Any complex concept that benefits from visualization
For detailed guidance on creating schematics, refer to the scientific-schematics skill documentation.
---
## Workflow Decision Tree
### Reading/Analyzing Content
Use "Text extraction" or "Raw XML access" sections below
### Creating New Document
Use "Creating a new Word document" workflow
### Editing Existing Document
- **Your own document + simple changes**
Use "Basic OOXML editing" workflow
- **Someone else's document**
Use **"Redlining workflow"** (recommended default)
- **Legal, academic, business, or government docs**
Use **"Redlining workflow"** (required)
## Reading and analyzing content
### Text extraction
To read the text contents of a document, convert the document to markdown using pandoc. Pandoc provides excellent support for preserving document structure and can show tracked changes:
```bash
# Convert document to markdown with tracked changes
pandoc --track-changes=all path-to-file.docx -o output.md
# Options: --track-changes=accept/reject/all
```
### Raw XML access
Raw XML access is required for: comments, complex formatting, document structure, embedded media, and metadata. For any of these features, unpack a document and read its raw XML contents.
#### Unpacking a file
`python ooxml/scripts/unpack.py <office_file> <output_directory>`
#### Key file structures
* `word/document.xml` - Main document contents
* `word/comments.xml` - Comments referenced in document.xml
* `word/media/` - Embedded images and media files
* Tracked changes use `<w:ins>` (insertions) and `<w:del>` (deletions) tags
## Creating a new Word document
When creating a new Word document from scratch, use **docx-js**, which allows you to create Word documents using JavaScript/TypeScript.
### Workflow
1. **MANDATORY - READ ENTIRE FILE**: Read [`docx-js.md`](docx-js.md) (~500 lines) completely from start to finish. **NEVER set any range limits when reading this file.** Read the full file content for detailed syntax, critical formatting rules, and best practices before proceeding with document creation.
2. Create a JavaScript/TypeScript file using Document, Paragraph, TextRun components (You can assume all dependencies are installed, but if not, refer to the dependencies section below)
3. Export as .docx using Packer.toBuffer()
## Editing an existing Word document
When editing an existing Word document, use the **Document library** (a Python library for OOXML manipulation). The library automatically handles infrastructure setup and provides methods for document manipulation. For complex scenarios, you can access the underlying DOM directly through the library.
### Workflow
1. **MANDATORY - READ ENTIRE FILE**: Read [`ooxml.md`](ooxml.md) (~600 lines) completely from start to finish. **NEVER set any range limits when reading this file.** Read the full file content for the Document library API and XML patterns for directly editing document files.
2. Unpack the document: `python ooxml/scripts/unpack.py <office_file> <output_directory>`
3. Create and run a Python script using the Document library (see "Document Library" section in ooxml.md)
4. Pack the final document: `python ooxml/scripts/pack.py <input_directory> <office_file>`
The Document library provides both high-level methods for common operations and direct DOM access for complex scenarios.
## Redlining workflow for document review
This workflow allows planning comprehensive tracked changes using markdown before implementing them in OOXML. **CRITICAL**: For complete tracked changes, implement ALL changes systematically.
**Batching Strategy**: Group related changes into batches of 3-10 changes. This makes debugging manageable while maintaining efficiency. Test each batch before moving to the next.
**Principle: Minimal, Precise Edits**
When implementing tracked changes, only mark text that actually changes. Repeating unchanged text makes edits harder to review and appears unprofessional. Break replacements into: [unchanged text] + [deletion] + [insertion] + [unchanged text]. Preserve the original run's RSID for unchanged text by extracting the `<w:r>` element from the original and reusing it.
Example - Changing "30 days" to "60 days" in a sentence:
```python
# BAD - Replaces entire sentence
'<w:del><w:r><w:delText>The term is 30 days.</w:delText></w:r></w:del><w:ins><w:r><w:t>The term is 60 days.</w:t></w:r></w:ins>'
# GOOD - Only marks what changed, preserves original <w:r> for unchanged text
'<w:r w:rsidR="00AB12CD"><w:t>The term is </w:t></w:r><w:del><w:r><w:delText>30</w:delText></w:r></w:del><w:ins><w:r><w:t>60</w:t></w:r></w:ins><w:r w:rsidR="00AB12CD"><w:t> days.</w:t></w:r>'
```
### Tracked changes workflow
1. **Get markdown representation**: Convert document to markdown with tracked changes preserved:
```bash
pandoc --track-changes=all path-to-file.docx -o current.md
```
2. **Identify and group changes**: Review the document and identify ALL changes needed, organizing them into logical batches:
**Location methods** (for finding changes in XML):
- Section/heading numbers (e.g., "Section 3.2", "Article IV")
- Paragraph identifiers if numbered
- Grep patterns with unique surrounding text
- Document structure (e.g., "first paragraph", "signature block")
- **DO NOT use markdown line numbers** - they don't map to XML structure
**Batch organization** (group 3-10 related changes per batch):
- By section: "Batch 1: Section 2 amendments", "Batch 2: Section 5 updates"
- By type: "Batch 1: Date corrections", "Batch 2: Party name changes"
- By complexity: Start with simple text replacements, then tackle complex structural changes
- Sequential: "Batch 1: Pages 1-3", "Batch 2: Pages 4-6"
3. **Read documentation and unpack**:
- **MANDATORY - READ ENTIRE FILE**: Read [`ooxml.md`](ooxml.md) (~600 lines) completely from start to finish. **NEVER set any range limits when reading this file.** Pay special attention to the "Document Library" and "Tracked Change Patterns" sections.
- **Unpack the document**: `python ooxml/scripts/unpack.py <file.docx> <dir>`
- **Note the suggested RSID**: The unpack script will suggest an RSID to use for your tracked changes. Copy this RSID for use in step 4b.
4. **Implement changes in batches**: Group changes logically (by section, by type, or by proximity) and implement them together in a single script. This approach:
- Makes debugging easier (smaller batch = easier to isolate errors)
- Allows incremental progress
- Maintains efficiency (batch size of 3-10 changes works well)
**Suggested batch groupings:**
- By document section (e.g., "Section 3 changes", "Definitions", "Termination clause")
- By change type (e.g., "Date changes", "Party name updates", "Legal term replacements")
- By proximity (e.g., "Changes on pages 1-3", "Changes in first half of document")
For each batch of related changes:
**a. Map text to XML**: Grep for text in `word/document.xml` to verify how text is split across `<w:r>` elements.
**b. Create and run script**: Use `get_node` to find nodes, implement changes, then `doc.save()`. See **"Document Library"** section in ooxml.md for patterns.
**Note**: Always grep `word/document.xml` immediately before writing a script to get current line numbers and verify text content. Line numbers change after each script run.
5. **Pack the document**: After all batches are complete, convert the unpacked directory back to .docx:
```bash
python ooxml/scripts/pack.py unpacked reviewed-document.docx
```
6. **Final verification**: Do a comprehensive check of the complete document:
- Convert final document to markdown:
```bash
pandoc --track-changes=all reviewed-document.docx -o verification.md
```
- Verify ALL changes were applied correctly:
```bash
grep "original phrase" verification.md # Should NOT find it
grep "replacement phrase" verification.md # Should find it
```
- Check that no unintended changes were introduced
## Converting Documents to Images
To visually analyze Word documents, convert them to images using a two-step process:
1. **Convert DOCX to PDF**:
```bash
soffice --headless --convert-to pdf document.docx
```
2. **Convert PDF pages to JPEG images**:
```bash
pdftoppm -jpeg -r 150 document.pdf page
```
This creates files like `page-1.jpg`, `page-2.jpg`, etc.
Options:
- `-r 150`: Sets resolution to 150 DPI (adjust for quality/size balance)
- `-jpeg`: Output JPEG format (use `-png` for PNG if preferred)
- `-f N`: First page to convert (e.g., `-f 2` starts from page 2)
- `-l N`: Last page to convert (e.g., `-l 5` stops at page 5)
- `page`: Prefix for output files
Example for specific range:
```bash
pdftoppm -jpeg -r 150 -f 2 -l 5 document.pdf page # Converts only pages 2-5
```
## Code Style Guidelines
**IMPORTANT**: When generating code for DOCX operations:
- Write concise code
- Avoid verbose variable names and redundant operations
- Avoid unnecessary print statements
## Dependencies
Required dependencies (install if not available):
- **pandoc**: `sudo apt-get install pandoc` (for text extraction)
- **docx**: `npm install -g docx` (for creating new documents)
- **LibreOffice**: `sudo apt-get install libreoffice` (for PDF conversion)
- **Poppler**: `sudo apt-get install poppler-utils` (for pdftoppm to convert PDF to images)
- **defusedxml**: `pip install defusedxml` (for secure XML parsing)

# DOCX Library Tutorial
Generate .docx files with JavaScript/TypeScript.
**Important: Read this entire document before starting.** Critical formatting rules and common pitfalls are covered throughout - skipping sections may result in corrupted files or rendering issues.
## Setup
Assumes docx is already installed globally
If not installed: `npm install -g docx`
```javascript
const { Document, Packer, Paragraph, TextRun, Table, TableRow, TableCell, ImageRun, Media,
Header, Footer, AlignmentType, PageOrientation, LevelFormat, ExternalHyperlink,
InternalHyperlink, TableOfContents, HeadingLevel, BorderStyle, WidthType, TabStopType,
TabStopPosition, UnderlineType, ShadingType, VerticalAlign, SymbolRun, PageNumber,
FootnoteReferenceRun, Footnote, PageBreak } = require('docx');
// Create & Save
const doc = new Document({ sections: [{ children: [/* content */] }] });
Packer.toBuffer(doc).then(buffer => fs.writeFileSync("doc.docx", buffer)); // Node.js
Packer.toBlob(doc).then(blob => { /* download logic */ }); // Browser
```
## Text & Formatting
```javascript
// IMPORTANT: Never use \n for line breaks - always use separate Paragraph elements
// ❌ WRONG: new TextRun("Line 1\nLine 2")
// ✅ CORRECT: new Paragraph({ children: [new TextRun("Line 1")] }), new Paragraph({ children: [new TextRun("Line 2")] })
// Basic text with all formatting options
new Paragraph({
alignment: AlignmentType.CENTER,
spacing: { before: 200, after: 200 },
indent: { left: 720, right: 720 },
children: [
new TextRun({ text: "Bold", bold: true }),
new TextRun({ text: "Italic", italics: true }),
new TextRun({ text: "Underlined", underline: { type: UnderlineType.DOUBLE, color: "FF0000" } }),
new TextRun({ text: "Colored", color: "FF0000", size: 28, font: "Arial" }), // Arial default
new TextRun({ text: "Highlighted", highlight: "yellow" }),
new TextRun({ text: "Strikethrough", strike: true }),
new TextRun({ text: "x2", superScript: true }),
new TextRun({ text: "H2O", subScript: true }),
new TextRun({ text: "SMALL CAPS", smallCaps: true }),
new SymbolRun({ char: "2022", font: "Symbol" }), // Bullet •
new SymbolRun({ char: "00A9", font: "Arial" }) // Copyright © - Arial for symbols
]
})
```
## Styles & Professional Formatting
```javascript
const doc = new Document({
styles: {
default: { document: { run: { font: "Arial", size: 24 } } }, // 12pt default
paragraphStyles: [
// Document title style - override built-in Title style
{ id: "Title", name: "Title", basedOn: "Normal",
run: { size: 56, bold: true, color: "000000", font: "Arial" },
paragraph: { spacing: { before: 240, after: 120 }, alignment: AlignmentType.CENTER } },
// IMPORTANT: Override built-in heading styles by using their exact IDs
{ id: "Heading1", name: "Heading 1", basedOn: "Normal", next: "Normal", quickFormat: true,
run: { size: 32, bold: true, color: "000000", font: "Arial" }, // 16pt
paragraph: { spacing: { before: 240, after: 240 }, outlineLevel: 0 } }, // Required for TOC
{ id: "Heading2", name: "Heading 2", basedOn: "Normal", next: "Normal", quickFormat: true,
run: { size: 28, bold: true, color: "000000", font: "Arial" }, // 14pt
paragraph: { spacing: { before: 180, after: 180 }, outlineLevel: 1 } },
// Custom styles use your own IDs
{ id: "myStyle", name: "My Style", basedOn: "Normal",
run: { size: 28, bold: true, color: "000000" },
paragraph: { spacing: { after: 120 }, alignment: AlignmentType.CENTER } }

run: { color: "FF0000", bold: true, underline: { type: UnderlineType.SINGLE } } }]
},
sections: [{
properties: { page: { margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 } } },
children: [
new Paragraph({ heading: HeadingLevel.TITLE, children: [new TextRun("Document Title")] }), // Uses overridden Title style
new Paragraph({ heading: HeadingLevel.HEADING_1, children: [new TextRun("Heading 1")] }), // Uses overridden Heading1 style

]
}]
});
```
**Professional Font Combinations:**
- **Arial (Headers) + Arial (Body)** - Most universally supported, clean and professional
- **Times New Roman (Headers) + Arial (Body)** - Classic serif headers with modern sans-serif body
- **Georgia (Headers) + Verdana (Body)** - Optimized for screen reading, elegant contrast
**Key Styling Principles:**
- **Override built-in styles**: Use exact IDs like "Heading1", "Heading2", "Heading3" to override Word's built-in heading styles
- **HeadingLevel constants**: `HeadingLevel.HEADING_1` uses "Heading1" style, `HeadingLevel.HEADING_2` uses "Heading2" style, etc.
- **Include outlineLevel**: Set `outlineLevel: 0` for H1, `outlineLevel: 1` for H2, etc. to ensure TOC works correctly
- **Use custom styles** instead of inline formatting for consistency
- **Set a default font** using `styles.default.document.run.font` - Arial is universally supported
- **Establish visual hierarchy** with different font sizes (titles > headers > body)
- **Add proper spacing** with `before` and `after` paragraph spacing
- **Use colors sparingly**: Default to black (000000) and shades of gray for titles and headings (heading 1, heading 2, etc.)
- **Set consistent margins** (1440 = 1 inch is standard)
## Lists (ALWAYS USE PROPER LISTS - NEVER USE UNICODE BULLETS)
```javascript
// Bullets - ALWAYS use the numbering config, NOT unicode symbols
// CRITICAL: Use LevelFormat.BULLET constant, NOT the string "bullet"
const doc = new Document({
numbering: {
config: [
{ reference: "bullet-list",
levels: [{ level: 0, format: LevelFormat.BULLET, text: "•", alignment: AlignmentType.LEFT,
style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] },
{ reference: "first-numbered-list",
levels: [{ level: 0, format: LevelFormat.DECIMAL, text: "%1.", alignment: AlignmentType.LEFT,
style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] },
{ reference: "second-numbered-list", // Different reference = restarts at 1
levels: [{ level: 0, format: LevelFormat.DECIMAL, text: "%1.", alignment: AlignmentType.LEFT,
style: { paragraph: { indent: { left: 720, hanging: 360 } } } }] }
]
},
sections: [{
children: [
// Bullet list items
new Paragraph({ numbering: { reference: "bullet-list", level: 0 },
children: [new TextRun("First bullet point")] }),
new Paragraph({ numbering: { reference: "bullet-list", level: 0 },
children: [new TextRun("Second bullet point")] }),
// Numbered list items
new Paragraph({ numbering: { reference: "first-numbered-list", level: 0 },
children: [new TextRun("First numbered item")] }),
new Paragraph({ numbering: { reference: "first-numbered-list", level: 0 },
children: [new TextRun("Second numbered item")] }),
// ⚠️ CRITICAL: Different reference = INDEPENDENT list that restarts at 1
// Same reference = CONTINUES previous numbering
new Paragraph({ numbering: { reference: "second-numbered-list", level: 0 },
children: [new TextRun("Starts at 1 again (because different reference)")] })
]
}]
});
// ⚠️ CRITICAL NUMBERING RULE: Each reference creates an INDEPENDENT numbered list
// - Same reference = continues numbering (1, 2, 3... then 4, 5, 6...)
// - Different reference = restarts at 1 (1, 2, 3... then 1, 2, 3...)
// Use unique reference names for each separate numbered section!
// ⚠️ CRITICAL: NEVER use unicode bullets - they create fake lists that don't work properly
// new TextRun("• Item") // WRONG
// new SymbolRun({ char: "2022" }) // WRONG
// ✅ ALWAYS use numbering config with LevelFormat.BULLET for real Word lists
```
## Tables
```javascript
// Complete table with margins, borders, headers, and bullet points
const tableBorder = { style: BorderStyle.SINGLE, size: 1, color: "CCCCCC" };
const cellBorders = { top: tableBorder, bottom: tableBorder, left: tableBorder, right: tableBorder };
new Table({
columnWidths: [4680, 4680], // ⚠️ CRITICAL: Set column widths at table level - values in DXA (twentieths of a point)
margins: { top: 100, bottom: 100, left: 180, right: 180 }, // Set once for all cells
rows: [
new TableRow({
tableHeader: true,
children: [
new TableCell({
borders: cellBorders,
width: { size: 4680, type: WidthType.DXA }, // ALSO set width on each cell
// ⚠️ CRITICAL: Always use ShadingType.CLEAR to prevent black backgrounds in Word.
shading: { fill: "D5E8F0", type: ShadingType.CLEAR },
verticalAlign: VerticalAlign.CENTER,
children: [new Paragraph({
alignment: AlignmentType.CENTER,
children: [new TextRun({ text: "Header", bold: true, size: 22 })]
})]
}),
new TableCell({
borders: cellBorders,
width: { size: 4680, type: WidthType.DXA }, // ALSO set width on each cell
shading: { fill: "D5E8F0", type: ShadingType.CLEAR },
children: [new Paragraph({
alignment: AlignmentType.CENTER,
children: [new TextRun({ text: "Bullet Points", bold: true, size: 22 })]
})]
})
]
}),
new TableRow({
children: [
new TableCell({
borders: cellBorders,
width: { size: 4680, type: WidthType.DXA }, // ALSO set width on each cell
children: [new Paragraph({ children: [new TextRun("Regular data")] })]
}),
new TableCell({
borders: cellBorders,
width: { size: 4680, type: WidthType.DXA }, // ALSO set width on each cell
children: [
new Paragraph({
numbering: { reference: "bullet-list", level: 0 },
children: [new TextRun("First bullet point")]
}),
new Paragraph({
numbering: { reference: "bullet-list", level: 0 },
children: [new TextRun("Second bullet point")]
})
]
})
]
})
]
})
```
**IMPORTANT: Table Width & Borders**
- Use BOTH `columnWidths: [width1, width2, ...]` array AND `width: { size: X, type: WidthType.DXA }` on each cell
- Values in DXA (twentieths of a point): 1440 = 1 inch, Letter usable width = 9360 DXA (with 1" margins)
- Apply borders to individual `TableCell` elements, NOT the `Table` itself
**Precomputed Column Widths (Letter size with 1" margins = 9360 DXA total):**
- **2 columns:** `columnWidths: [4680, 4680]` (equal width)
- **3 columns:** `columnWidths: [3120, 3120, 3120]` (equal width)
## Links & Navigation
```javascript
// TOC (requires headings) - CRITICAL: Use HeadingLevel only, NOT custom styles
// ❌ WRONG: new Paragraph({ heading: HeadingLevel.HEADING_1, style: "customHeader", children: [new TextRun("Title")] })
// ✅ CORRECT: new Paragraph({ heading: HeadingLevel.HEADING_1, children: [new TextRun("Title")] })
new TableOfContents("Table of Contents", { hyperlink: true, headingStyleRange: "1-3" }),
// External link
new Paragraph({
children: [new ExternalHyperlink({
children: [new TextRun({ text: "Google", style: "Hyperlink" })],
link: "https://www.google.com"
})]
}),
// Internal link & bookmark
new Paragraph({
children: [new InternalHyperlink({
children: [new TextRun({ text: "Go to Section", style: "Hyperlink" })],
anchor: "section1"
})]
}),
new Paragraph({
children: [new TextRun("Section Content")],
bookmark: { id: "section1", name: "section1" }
}),
```
## Images & Media
```javascript
// Basic image with sizing & positioning
// CRITICAL: Always specify 'type' parameter - it's REQUIRED for ImageRun
new Paragraph({
alignment: AlignmentType.CENTER,
children: [new ImageRun({
type: "png", // NEW REQUIREMENT: Must specify image type (png, jpg, jpeg, gif, bmp, svg)
data: fs.readFileSync("image.png"),
transformation: { width: 200, height: 150, rotation: 0 }, // rotation in degrees
altText: { title: "Logo", description: "Company logo", name: "Name" } // IMPORTANT: All three fields are required
})]
})
```
## Page Breaks
```javascript
// Manual page break
new Paragraph({ children: [new PageBreak()] }),
// Page break before paragraph
new Paragraph({
pageBreakBefore: true,
children: [new TextRun("This starts on a new page")]
})
// ⚠️ CRITICAL: NEVER use PageBreak standalone - it will create invalid XML that Word cannot open
// ❌ WRONG: new PageBreak()
// ✅ CORRECT: new Paragraph({ children: [new PageBreak()] })
```
## Headers/Footers & Page Setup
```javascript
const doc = new Document({
sections: [{
properties: {
page: {
margin: { top: 1440, right: 1440, bottom: 1440, left: 1440 }, // 1440 = 1 inch
size: { orientation: PageOrientation.LANDSCAPE },
pageNumbers: { start: 1, formatType: "decimal" } // "upperRoman", "lowerRoman", "upperLetter", "lowerLetter"
}
},
headers: {
default: new Header({ children: [new Paragraph({
alignment: AlignmentType.RIGHT,
children: [new TextRun("Header Text")]
})] })
},
footers: {
default: new Footer({ children: [new Paragraph({
alignment: AlignmentType.CENTER,
children: [new TextRun("Page "), new TextRun({ children: [PageNumber.CURRENT] }), new TextRun(" of "), new TextRun({ children: [PageNumber.TOTAL_PAGES] })]
})] })
},
children: [/* content */]
}]
});
```
## Tabs
```javascript
new Paragraph({
tabStops: [
{ type: TabStopType.LEFT, position: TabStopPosition.MAX / 4 },
{ type: TabStopType.CENTER, position: TabStopPosition.MAX / 2 },
{ type: TabStopType.RIGHT, position: TabStopPosition.MAX * 3 / 4 }
],
children: [new TextRun("Left\tCenter\tRight")]
})
```
## Constants & Quick Reference
- **Underlines:** `SINGLE`, `DOUBLE`, `WAVY`, `DASH`
- **Borders:** `SINGLE`, `DOUBLE`, `DASHED`, `DOTTED`
- **Numbering:** `DECIMAL` (1,2,3), `UPPER_ROMAN` (I,II,III), `LOWER_LETTER` (a,b,c)
- **Tabs:** `LEFT`, `CENTER`, `RIGHT`, `DECIMAL`
- **Symbols:** `"2022"` (•), `"00A9"` (©), `"00AE"` (®), `"2122"` (™), `"00B0"` (°), `"F070"` (✓), `"F0FC"` (✗)
## Critical Issues & Common Mistakes
- **CRITICAL: PageBreak must ALWAYS be inside a Paragraph** - standalone PageBreak creates invalid XML that Word cannot open
- **ALWAYS use ShadingType.CLEAR for table cell shading** - Never use ShadingType.SOLID (causes black background).
- Measurements in DXA (1440 = 1 inch) | Each table cell needs ≥1 Paragraph | TOC requires HeadingLevel styles only
- **ALWAYS use custom styles** with Arial font for professional appearance and proper visual hierarchy
- **ALWAYS set a default font** using `styles.default.document.run.font` - Arial recommended
- **ALWAYS use columnWidths array for tables** + individual cell widths for compatibility
- **NEVER use unicode symbols for bullets** - always use proper numbering configuration with `LevelFormat.BULLET` constant (NOT the string "bullet")
- **NEVER use \n for line breaks anywhere** - always use separate Paragraph elements for each line
- **ALWAYS use TextRun objects within Paragraph children** - never use text property directly on Paragraph
- **CRITICAL for images**: ImageRun REQUIRES `type` parameter - always specify "png", "jpg", "jpeg", "gif", "bmp", or "svg"
- **CRITICAL for bullets**: Must use `LevelFormat.BULLET` constant, not string "bullet", and include `text: "•"` for the bullet character
- **CRITICAL for numbering**: Each numbering reference creates an INDEPENDENT list. Same reference = continues numbering (1,2,3 then 4,5,6). Different reference = restarts at 1 (1,2,3 then 1,2,3). Use unique reference names for each separate numbered section!
- **CRITICAL for TOC**: When using TableOfContents, headings must use HeadingLevel ONLY - do NOT add custom styles to heading paragraphs or TOC will break
- **Tables**: Set `columnWidths` array + individual cell widths, apply borders to cells not table
- **Set table margins at TABLE level** for consistent cell padding (avoids repetition per cell)

# Office Open XML Technical Reference
**Important: Read this entire document before starting.** This document covers:
- [Technical Guidelines](#technical-guidelines) - Schema compliance rules and validation requirements
- [Document Content Patterns](#document-content-patterns) - XML patterns for headings, lists, tables, formatting, etc.
- [Document Library (Python)](#document-library-python) - Recommended approach for OOXML manipulation with automatic infrastructure setup
- [Tracked Changes (Redlining)](#tracked-changes-redlining) - XML patterns for implementing tracked changes
## Technical Guidelines
### Schema Compliance
- **Element ordering in `<w:pPr>`**: `<w:pStyle>`, `<w:numPr>`, `<w:spacing>`, `<w:ind>`, `<w:jc>`
- **Whitespace**: Add `xml:space='preserve'` to `<w:t>` elements with leading/trailing spaces
- **Unicode**: Escape characters in ASCII content: `"` becomes `&#8220;`
- **Character encoding reference**: Curly quotes `""` become `&#8220;&#8221;`, apostrophe `'` becomes `&#8217;`, em-dash `—` becomes `&#8212;`
- **Tracked changes**: Use `<w:del>` and `<w:ins>` tags with `w:author="Claude"` outside `<w:r>` elements
- **Critical**: `<w:ins>` closes with `</w:ins>`, `<w:del>` closes with `</w:del>` - never mix
- **RSIDs must be 8-digit hex**: Use values like `00AB1234` (only 0-9, A-F characters)
- **trackRevisions placement**: Add `<w:trackRevisions/>` after `<w:proofState>` in settings.xml
- **Images**: Add to `word/media/`, reference in `document.xml`, set dimensions to prevent overflow
## Document Content Patterns
### Basic Structure
```xml
<w:p>
<w:r><w:t>Text content</w:t></w:r>

<w:spacing w:before="240"/>
</w:pPr>
<w:r><w:t>First item</w:t></w:r>
</w:p>
<!-- Restart numbered list at 1 - use different numId -->
<w:p>
<w:pPr>
<w:pStyle w:val="ListParagraph"/>
<w:numPr><w:ilvl w:val="0"/><w:numId w:val="2"/></w:numPr>
<w:spacing w:before="240"/>
</w:pPr>
<w:r><w:t>New list item 1</w:t></w:r>

<w:p><w:r><w:t>Cell 2</w:t></w:r></w:p>
</w:tc>
</w:tr>
</w:tbl>
```
### Layout
```xml
<!-- Page break before new section (common pattern) -->
<w:p>
<w:r>
<w:br w:type="page"/>
</w:r>
</w:p>
<w:p>
<w:pPr>
<w:pStyle w:val="Heading1"/>
</w:pPr>
<w:r>
<w:t>New Section Title</w:t>
</w:r>
</w:p>
<!-- Centered paragraph -->
<w:p>
<w:pPr>
<w:spacing w:before="240" w:after="0"/>
<w:jc w:val="center"/>
</w:pPr>
<w:r><w:t>Centered text</w:t></w:r>
</w:p>
<!-- Font change - paragraph level (applies to all runs) -->
<w:p>
<w:pPr>
<w:rPr><w:rFonts w:ascii="Courier New" w:hAnsi="Courier New"/></w:rPr>
</w:pPr>
<w:r><w:t>Monospace text</w:t></w:r>
</w:p>
<!-- Font change - run level (specific to this text) -->
<w:p>
<w:r>
<w:rPr><w:rFonts w:ascii="Courier New" w:hAnsi="Courier New"/></w:rPr>
<w:t>This text is Courier New</w:t>
</w:r>
<w:r><w:t> and this text uses default font</w:t></w:r>
</w:p>
```
## File Updates
When adding content, update these files:
**`word/_rels/document.xml.rels`:**
```xml
<Relationship Id="rId1" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/numbering" Target="numbering.xml"/>
<Relationship Id="rId5" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="media/image1.png"/>
```
**`[Content_Types].xml`:**
```xml
<Default Extension="png" ContentType="image/png"/>
<Override PartName="/word/numbering.xml" ContentType="application/vnd.openxmlformats-officedocument.wordprocessingml.numbering+xml"/>
```
### Images
**CRITICAL**: Calculate dimensions to prevent page overflow and maintain aspect ratio.
```xml
<!-- Minimal required structure -->
<w:p>
<w:r>
<w:drawing>
<wp:inline>
<wp:extent cx="2743200" cy="1828800"/>
<wp:docPr id="1" name="Picture 1"/>
<a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main">
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/picture">
<pic:pic xmlns:pic="http://schemas.openxmlformats.org/drawingml/2006/picture">
<pic:nvPicPr>
<pic:cNvPr id="0" name="image1.png"/>
<pic:cNvPicPr/>
</pic:nvPicPr>
<pic:blipFill>
<a:blip r:embed="rId5"/>
<!-- Add for stretch fill with aspect ratio preservation -->
<a:stretch>
<a:fillRect/>
</a:stretch>
</pic:blipFill>
<pic:spPr>
<a:xfrm>
<a:ext cx="2743200" cy="1828800"/>
</a:xfrm>
<a:prstGeom prst="rect"/>
</pic:spPr>
</pic:pic>
</a:graphicData>
</a:graphic>
</wp:inline>
</w:drawing>
</w:r>
</w:p>
```
### Links (Hyperlinks)
**IMPORTANT**: All hyperlinks (both internal and external) require the Hyperlink style to be defined in styles.xml. Without this style, links will look like regular text instead of blue underlined clickable links.
**External Links:**
```xml
<!-- In document.xml -->
<w:hyperlink r:id="rId5">
<w:r>
<w:rPr><w:rStyle w:val="Hyperlink"/></w:rPr>
<w:t>Link Text</w:t>
</w:r>
</w:hyperlink>
<!-- In word/_rels/document.xml.rels -->
<Relationship Id="rId5" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/hyperlink"
Target="https://www.example.com/" TargetMode="External"/>
```
**Internal Links:**
```xml
<!-- Link to bookmark -->
<w:hyperlink w:anchor="myBookmark">
<w:r>
<w:rPr><w:rStyle w:val="Hyperlink"/></w:rPr>
<w:t>Link Text</w:t>
</w:r>
</w:hyperlink>
<!-- Bookmark target -->
<w:bookmarkStart w:id="0" w:name="myBookmark"/>
<w:r><w:t>Target content</w:t></w:r>
<w:bookmarkEnd w:id="0"/>
```
**Hyperlink Style (required in styles.xml):**
```xml
<w:style w:type="character" w:styleId="Hyperlink">
<w:name w:val="Hyperlink"/>
<w:basedOn w:val="DefaultParagraphFont"/>
<w:uiPriority w:val="99"/>
<w:unhideWhenUsed/>
<w:rPr>
<w:color w:val="467886" w:themeColor="hyperlink"/>
<w:u w:val="single"/>
</w:rPr>
</w:style>
```
## Document Library (Python)
Use the Document class from `scripts/document.py` for all tracked changes and comments. It automatically handles infrastructure setup (people.xml, RSIDs, settings.xml, comment files, relationships, content types). Only use direct XML manipulation for complex scenarios not supported by the library.
**Working with Unicode and Entities:**
- **Searching**: Both entity notation and Unicode characters work - `contains="&#8220;Company"` and `contains="\u201cCompany"` find the same text
- **Replacing**: Use either entities (`&#8220;`) or Unicode (`\u201c`) - both work and will be converted appropriately based on the file's encoding (ascii → entities, utf-8 → Unicode)
### Initialization
**Find the docx skill root** (directory containing `scripts/` and `ooxml/`):
```bash
# Search for document.py to locate the skill root
# Note: /mnt/skills is used here as an example; check your context for the actual location
find /mnt/skills -name "document.py" -path "*/docx/scripts/*" 2>/dev/null | head -1
# Example output: /mnt/skills/docx/scripts/document.py
# Skill root is: /mnt/skills/docx
```
**Run your script with PYTHONPATH** set to the docx skill root:
```bash
PYTHONPATH=/mnt/skills/docx python your_script.py
```
**In your script**, import from the skill root:
```python
from scripts.document import Document, DocxXMLEditor
# Basic initialization (automatically creates temp copy and sets up infrastructure)
doc = Document('unpacked')
# Customize author and initials
doc = Document('unpacked', author="John Doe", initials="JD")
# Enable track revisions mode
doc = Document('unpacked', track_revisions=True)
# Specify custom RSID (auto-generated if not provided)
doc = Document('unpacked', rsid="07DC5ECB")
```
### Creating Tracked Changes
**CRITICAL**: Only mark text that actually changes. Keep ALL unchanged text outside `<w:del>`/`<w:ins>` tags. Marking unchanged text makes edits unprofessional and harder to review.
**Attribute Handling**: The Document class auto-injects attributes (w:id, w:date, w:rsidR, w:rsidDel, w16du:dateUtc, xml:space) into new elements. When preserving unchanged text from the original document, copy the original `<w:r>` element with its existing attributes to maintain document integrity.
**Method Selection Guide**:
- **Adding your own changes to regular text**: Use `replace_node()` with `<w:del>`/`<w:ins>` tags, or `suggest_deletion()` for removing entire `<w:r>` or `<w:p>` elements
- **Partially modifying another author's tracked change**: Use `replace_node()` to nest your changes inside their `<w:ins>`/`<w:del>`
- **Completely rejecting another author's insertion**: Use `revert_insertion()` on the `<w:ins>` element (NOT `suggest_deletion()`)
- **Completely rejecting another author's deletion**: Use `revert_deletion()` on the `<w:del>` element to restore deleted content using tracked changes
```python
# Minimal edit - change one word: "The report is monthly" → "The report is quarterly"
# Original: <w:r w:rsidR="00AB12CD"><w:rPr><w:rFonts w:ascii="Calibri"/></w:rPr><w:t>The report is monthly</w:t></w:r>
node = doc["word/document.xml"].get_node(tag="w:r", contains="The report is monthly")
rpr = tags[0].toxml() if (tags := node.getElementsByTagName("w:rPr")) else ""
replacement = f'<w:r w:rsidR="00AB12CD">{rpr}<w:t>The report is </w:t></w:r><w:del><w:r>{rpr}<w:delText>monthly</w:delText></w:r></w:del><w:ins><w:r>{rpr}<w:t>quarterly</w:t></w:r></w:ins>'
doc["word/document.xml"].replace_node(node, replacement)
# Minimal edit - change number: "within 30 days" → "within 45 days"
# Original: <w:r w:rsidR="00XYZ789"><w:rPr><w:rFonts w:ascii="Calibri"/></w:rPr><w:t>within 30 days</w:t></w:r>

# doc["word/document.xml"].insert_after(target_para, spacing + tracked_para)
```
### Adding Comments
```python
# Add comment spanning two existing tracked changes
# Note: w:id is auto-generated. Only search by w:id if you know it from XML inspection
start_node = doc["word/document.xml"].get_node(tag="w:del", attrs={"w:id": "1"})
end_node = doc["word/document.xml"].get_node(tag="w:ins", attrs={"w:id": "2"})
doc.add_comment(start=start_node, end=end_node, text="Explanation of this change")
# Add comment on a paragraph
para = doc["word/document.xml"].get_node(tag="w:p", contains="paragraph text")
doc.add_comment(start=para, end=para, text="Comment on this paragraph")
# Add comment on newly created tracked change
# First create the tracked change
node = doc["word/document.xml"].get_node(tag="w:r", contains="old")
new_nodes = doc["word/document.xml"].replace_node(
node,
'<w:del><w:r><w:delText>old</w:delText></w:r></w:del><w:ins><w:r><w:t>new</w:t></w:r></w:ins>'
)
# Then add comment on the newly created elements
# new_nodes[0] is the <w:del>, new_nodes[1] is the <w:ins>
doc.add_comment(start=new_nodes[0], end=new_nodes[1], text="Changed old to new per requirements")
# Reply to existing comment
doc.reply_to_comment(parent_comment_id=0, text="I agree with this change")
```
### Rejecting Tracked Changes
**IMPORTANT**: Use `revert_insertion()` to reject insertions and `revert_deletion()` to restore deletions using tracked changes. Use `suggest_deletion()` only for regular unmarked content.
```python
# Reject insertion (wraps it in deletion)
# Use this when another author inserted text that you want to delete
ins = doc["word/document.xml"].get_node(tag="w:ins", attrs={"w:id": "5"})
nodes = doc["word/document.xml"].revert_insertion(ins) # Returns [ins]
# Reject deletion (creates insertion to restore deleted content)
# Use this when another author deleted text that you want to restore
del_elem = doc["word/document.xml"].get_node(tag="w:del", attrs={"w:id": "3"})
nodes = doc["word/document.xml"].revert_deletion(del_elem) # Returns [del_elem, new_ins]
# Reject all insertions in a paragraph
para = doc["word/document.xml"].get_node(tag="w:p", contains="paragraph text")
nodes = doc["word/document.xml"].revert_insertion(para) # Returns [para]
# Reject all deletions in a paragraph
para = doc["word/document.xml"].get_node(tag="w:p", contains="paragraph text")
nodes = doc["word/document.xml"].revert_deletion(para) # Returns [para]
```
### Inserting Images
**CRITICAL**: The Document class works with a temporary copy at `doc.unpacked_path`. Always copy images to this temp directory, not the original unpacked folder.
```python
from PIL import Image
import shutil, os
# Initialize document first
doc = Document('unpacked')
# Copy image and calculate full-width dimensions with aspect ratio
media_dir = os.path.join(doc.unpacked_path, 'word/media')
os.makedirs(media_dir, exist_ok=True)
shutil.copy('image.png', os.path.join(media_dir, 'image1.png'))
img = Image.open(os.path.join(media_dir, 'image1.png'))
width_emus = int(6.5 * 914400) # 6.5" usable width, 914400 EMUs/inch
height_emus = int(width_emus * img.size[1] / img.size[0])
# Add relationship and content type
rels_editor = doc['word/_rels/document.xml.rels']
next_rid = rels_editor.get_next_rid()
rels_editor.append_to(rels_editor.dom.documentElement,
f'<Relationship Id="{next_rid}" Type="http://schemas.openxmlformats.org/officeDocument/2006/relationships/image" Target="media/image1.png"/>')
doc['[Content_Types].xml'].append_to(doc['[Content_Types].xml'].dom.documentElement,
'<Default Extension="png" ContentType="image/png"/>')
# Insert image
node = doc["word/document.xml"].get_node(tag="w:p", line_number=100)
doc["word/document.xml"].insert_after(node, f'''<w:p>
<w:r>
<w:drawing>
<wp:inline distT="0" distB="0" distL="0" distR="0">
<wp:extent cx="{width_emus}" cy="{height_emus}"/>
<wp:docPr id="1" name="Picture 1"/>
<a:graphic xmlns:a="http://schemas.openxmlformats.org/drawingml/2006/main">
<a:graphicData uri="http://schemas.openxmlformats.org/drawingml/2006/picture">
<pic:pic xmlns:pic="http://schemas.openxmlformats.org/drawingml/2006/picture">
<pic:nvPicPr><pic:cNvPr id="1" name="image1.png"/><pic:cNvPicPr/></pic:nvPicPr>
<pic:blipFill><a:blip r:embed="{next_rid}"/><a:stretch><a:fillRect/></a:stretch></pic:blipFill>

</pic:pic>
</a:graphicData>
</a:graphic>
</wp:inline>
</w:drawing>
</w:r>
</w:p>''')
```
### Getting Nodes
```python
# By text content
node = doc["word/document.xml"].get_node(tag="w:p", contains="specific text")
# By line range
para = doc["word/document.xml"].get_node(tag="w:p", line_number=range(100, 150))
# By attributes
node = doc["word/document.xml"].get_node(tag="w:del", attrs={"w:id": "1"})
# By exact line number (must be line number where tag opens)
para = doc["word/document.xml"].get_node(tag="w:p", line_number=42)
# Combine filters
node = doc["word/document.xml"].get_node(tag="w:r", line_number=range(40, 60), contains="text")
# Disambiguate when text appears multiple times - add line_number range
node = doc["word/document.xml"].get_node(tag="w:r", contains="Section", line_number=range(2400, 2500))
```
### Saving
```python
# Save with automatic validation (copies back to original directory)
doc.save() # Validates by default, raises error if validation fails
# Save to different location
doc.save('modified-unpacked')
# Skip validation (debugging only - needing this in production indicates XML issues)
doc.save(validate=False)
```
### Direct DOM Manipulation
For complex scenarios not covered by the library:
```python
# Access any XML file
editor = doc["word/document.xml"]
editor = doc["word/comments.xml"]
# Direct DOM access (defusedxml.minidom.Document)
node = doc["word/document.xml"].get_node(tag="w:p", line_number=5)
parent = node.parentNode
parent.removeChild(node)
parent.appendChild(node) # Move to end
# General document manipulation (without tracked changes)
old_node = doc["word/document.xml"].get_node(tag="w:p", contains="original text")
doc["word/document.xml"].replace_node(old_node, "<w:p><w:r><w:t>replacement text</w:t></w:r></w:p>")
# Multiple insertions - use return value to maintain order
node = doc["word/document.xml"].get_node(tag="w:r", line_number=100)
nodes = doc["word/document.xml"].insert_after(node, "<w:r><w:t>A</w:t></w:r>")
nodes = doc["word/document.xml"].insert_after(nodes[-1], "<w:r><w:t>B</w:t></w:r>")
nodes = doc["word/document.xml"].insert_after(nodes[-1], "<w:r><w:t>C</w:t></w:r>")
# Results in: original_node, A, B, C
```
## Tracked Changes (Redlining)
**Use the Document class above for all tracked changes.** The patterns below are for reference when constructing replacement XML strings.
### Validation Rules
The validator checks that the document text matches the original after reverting Claude's changes. This means:
- **NEVER modify text inside another author's `<w:ins>` or `<w:del>` tags**
- **ALWAYS use nested deletions** to remove another author's insertions
- **Every edit must be properly tracked** with `<w:ins>` or `<w:del>` tags
### Tracked Change Patterns
**CRITICAL RULES**:
1. Never modify the content inside another author's tracked changes. Always use nested deletions.
2. **XML Structure**: Always place `<w:del>` and `<w:ins>` at paragraph level containing complete `<w:r>` elements. Never nest inside `<w:r>` elements - this creates invalid XML that breaks document processing.
**Text Insertion:**
```xml
<w:ins w:id="1" w:author="Claude" w:date="2025-07-30T23:05:00Z" w16du:dateUtc="2025-07-31T06:05:00Z">
<w:r w:rsidR="00792858">
<w:t>inserted text</w:t>
</w:r>
</w:ins>
```
**Text Deletion:**
```xml
<w:del w:id="2" w:author="Claude" w:date="2025-07-30T23:05:00Z" w16du:dateUtc="2025-07-31T06:05:00Z">
<w:r w:rsidDel="00792858">
<w:delText>deleted text</w:delText>
</w:r>
</w:del>
```
**Deleting Another Author's Insertion (MUST use nested structure):**
```xml
<!-- Nest deletion inside the original insertion -->
<w:ins w:author="Jane Smith" w:id="16">
<w:del w:author="Claude" w:id="40">
<w:r><w:delText>monthly</w:delText></w:r>
</w:del>
</w:ins>
<w:ins w:author="Claude" w:id="41">
<w:r><w:t>weekly</w:t></w:r>
</w:ins>
```
**Restoring Another Author's Deletion:**
```xml
<!-- Leave their deletion unchanged, add new insertion after it -->
<w:del w:author="Jane Smith" w:id="50">
<w:r><w:delText>within 30 days</w:delText></w:r>
</w:del>
<w:ins w:author="Claude" w:id="51">
<w:r><w:t>within 30 days</w:t></w:r>
</w:ins>
```

<xs:annotation>
<xs:documentation>
See http://www.w3.org/XML/1998/namespace.html and
http://www.w3.org/TR/REC-xml for information about this namespace.
This schema document describes the XML namespace, in a form
suitable for import by other schema documents.
Note that local names in this namespace are intended to be defined
only by the World Wide Web Consortium or its subgroups. The
following names are currently defined in this namespace and should
not be used with conflicting semantics by any Working Group,
specification, or document instance:
base (as an attribute name): denotes an attribute whose value
provides a URI to be used as the base for interpreting any
relative URIs in the scope of the element on which it
appears; its value is inherited. This name is reserved
by virtue of its definition in the XML Base specification.
lang (as an attribute name): denotes an attribute whose value
is a language code for the natural language of the content of
any element; its value is inherited. This name is reserved
by virtue of its definition in the XML specification.
space (as an attribute name): denotes an attribute whose
value is a keyword indicating what whitespace processing
discipline is intended for the content of the element; its
value is inherited. This name is reserved by virtue of its
definition in the XML specification.
Father (in any context at all): denotes Jon Bosak, the chair of
the original XML Working Group. This name is reserved by
the following decision of the W3C XML Plenary and
XML Coordination groups:
In appreciation for his vision, leadership and dedication
the W3C XML Plenary on this 10th day of February, 2000
reserves for Jon Bosak in perpetuity the XML name
xml:Father
</xs:documentation>
</xs:annotation>
<xs:annotation>
<xs:documentation>This schema defines attributes and an attribute group
suitable for use by
schemas wishing to allow xml:base, xml:lang or xml:space attributes
on elements they define.
To enable this, such a schema must import this schema
for the XML namespace, e.g. as follows:
&lt;schema . . .>
. . .
&lt;import namespace="http://www.w3.org/XML/1998/namespace"
schemaLocation="http://www.w3.org/2001/03/xml.xsd"/>
Subsequently, qualified reference to any of the attributes
or the group defined below will have the desired effect, e.g.
&lt;type . . .>
. . .
&lt;attributeGroup ref="xml:specialAttrs"/>
will define a type which will schema-validate an instance
element with any of those attributes</xs:documentation>
</xs:annotation>
<xs:annotation>
<xs:documentation>In keeping with the XML Schema WG's standard versioning
policy, this schema document will persist at
http://www.w3.org/2001/03/xml.xsd.
At the date of issue it can also be found at
http://www.w3.org/2001/xml.xsd.
The schema document at that URI may however change in the future,
in order to remain compatible with the latest version of XML Schema
itself. In other words, if the XML Schema namespace changes, the version
of this document at
http://www.w3.org/2001/xml.xsd will change
accordingly; the version at
http://www.w3.org/2001/03/xml.xsd will not change.
