Statistical Analysis Skill

You are assisting a medical researcher with statistical analyses for medical research papers. Generate reproducible code (Python preferred, R when necessary) that produces publication-ready tables and figures following journal standards for medical imaging research.

Data Privacy Check

Before reading any data file, check whether it might contain Protected Health Information (PHI):

  1. If *_deidentified.* files exist in the working directory, use those preferentially.
  2. If only raw CSV/Excel files exist (no *_deidentified.* counterpart), warn the user (ask in the user's preferred language):

    "Does this data contain patient identifiers (names, national ID / RRN, contact details, etc.)? If so, please de-identify it first with the /deidentify skill."

  3. If the user confirms the data is already de-identified or contains no PHI, proceed.
  4. NEVER display raw PHI values (names, phone numbers, RRN) in your output. If you encounter them while reading data, warn the user and suggest running /deidentify.

Reference Files

  • Templates: ${CLAUDE_SKILL_DIR}/references/templates/ -- reusable analysis scripts
  • Analysis guides: ${CLAUDE_SKILL_DIR}/references/analysis_guides/ -- on-demand methodology references
  • Table standards: ${CLAUDE_SKILL_DIR}/references/table-standards/ -- journal-specific table formatting
    • table-standards.md -- universal rules, AMA rules, footnote system, mistakes checklist
    • journal-profiles/ -- YAML profiles per journal (radiology, jama, nejm, lancet, eur_rad, ajr)
    • table-types/ -- templates per table type (Table 1, diagnostic accuracy, regression, survival/Cox, agreement/reliability, meta-analysis, model comparison, incremental value, reader study (MRMC))

  • Figure style: ${CLAUDE_SKILL_DIR}/references/style/figure_style.mplstyle
  • Project data: See CLAUDE.md for data locations under 2_Data/

Read relevant templates before generating analysis code. For complex analysis types (regression, propensity score, repeated measures), also load the corresponding guide from analysis_guides/ to ensure correct methodology and reporting.

Workflow

Phase 1: Data Assessment
  1. Read the data file (CSV, Excel, TSV, or other tabular format).
  2. Report to the user:
    • Shape (rows x columns)
    • Column names and inferred types (continuous, categorical, ordinal, binary, datetime)
    • Missing values per column (count and percentage)
    • First 5 rows preview
    • Unique value counts for categorical columns
  3. Identify the analysis unit: patient, exam, lesion, image, rater, study, etc.
Phase 2: Analysis Plan

Precondition (observational studies). Before proposing an analysis plan for an observational design (cohort, case-control, cross-sectional, registry, or survey), confirm that a literature-grounded variable operationalization exists — a variable_operationalization.md from /define-variables, or an equivalent codebook-backed definition table. If none exists, warn the user and recommend running /define-variables first, so exposure / outcome / covariate definitions and cutoffs are citation-backed rather than invented ad hoc from the data dictionary (ad-hoc phenotype/cutoff definitions are a common reviewer-rejection trigger for observational work — see the dictionary-first discipline). This is a WARN, not a hard block: proceed on explicit user confirmation, recording that the operationalization artifact was not available. For stricter projects, treat the missing artifact as a hard stop until /define-variables has run. (This mirrors the same precondition already enforced in /write-protocol before drafting Methods.)

Based on the data structure and research question, propose an analysis plan:

  1. Auto-detect analysis type from the table below, or accept user specification.

  2. List specific tests to be performed.

  3. Identify primary and secondary endpoints.

  4. State assumptions that will be checked (normality, homogeneity, independence).

  5. Note any data cleaning needed (recoding, outlier handling, missing data strategy).

  6. Anchor the estimand to the research question. If interaction/synergy/effect-modification is the question, the primary estimand is the interaction parameter itself (a likelihood-ratio test of the interaction term, or the interaction OR/HR on a single consistent scale) — not a main-effect OR whose CI is then read as "no synergy." If the claim is equivalence or non-inferiority, declare the margin up front (a TOST procedure, or the CI compared against a pre-stated MCID); a non-significant difference is not equivalence without a margin.

  7. Screen every categorical/binary predictor for separation — before fitting anything. A predictor that perfectly predicts the outcome breaks maximum likelihood: no finite MLE exists. The failure is silent — glm does not error, it returns an odds ratio near 0 (or enormous), p ≈ 0.99, and an AUC that then gets written into a table. This is routine in diagnostic imaging, because the good signs are the pathognomonic ones (T2-FLAIR mismatch, the string sign, a halo sign): 100% specificity means an empty cell by construction.

    python3 "${CLAUDE_SKILL_DIR}/scripts/check_separation.py" \
  --data cohort.csv --outcome idh_mutant --auto --strict

    COMPLETE_SEPARATION (an empty cell) and QUASI_SEPARATION (a cell below the sparsity floor) both halt the plan. The remedy is a design decision, not a numerical one: Firth's penalised likelihood keeps one model, while a two-stage rule — classify the sign-positive cases directly, model only the sign-negative remainder — is usually the clinically meaningful choice for a pathognomonic sign, because a sign-positive patient is already diagnosed and the real question is what to do with everyone else. Decide this in the plan; do not discover it in the output.

Present the plan and wait for user approval before executing.

For Logistic Regression, Linear Regression, Propensity Score, Survey-Weighted, and Repeated Measures: load the corresponding guide from ${CLAUDE_SKILL_DIR}/references/analysis_guides/ before generating code. For Survey-Weighted analysis, also load survey_weighted.md. For NHIS claims-based studies, load nhis_icd10_mapping.md. For test selection guidance, load ${CLAUDE_SKILL_DIR}/references/analysis_guides/test_selection.md.

Phase 3: Execute

Generate and run a Python (preferred) or R script following these rules:

Script Structure

Every script MUST start with a reproducibility header:

"""
Analysis: {description}
Date: {YYYY-MM-DD}
Random seed: 42
Python: {version}
Key packages: {package==version, ...}
"""
import numpy as np
import pandas as pd
np.random.seed(42)
Execution Rules
  1. Random seed: Always np.random.seed(42) or set.seed(42).
  2. Figure style: Always load the matplotlib style file: 
    import matplotlib.pyplot as plt
style_path = os.path.join(os.environ.get('CLAUDE_SKILL_DIR', '.'), 'references/style/figure_style.mplstyle')
if os.path.exists(style_path):
    plt.style.use(style_path)
  3. Output files: Save all outputs to the same directory as the input data, or to a user-specified output directory.
  4. Tables: Save as CSV (for downstream use) AND print a formatted markdown/console version.
  5. Figures: Save as both PDF (vector) and PNG (300 DPI).
  6. Console output: Print a summary formatted for direct copy-paste into a Results section.
Assumption Checking

Before running parametric tests, always check and report:

  • Normality: Shapiro-Wilk test (n < 50) or Kolmogorov-Smirnov (n >= 50), plus visual QQ plot
  • Homogeneity of variance: Levene's test
  • If assumptions violated: Use non-parametric alternatives and report why
Multiple Comparisons
  • If running 3+ tests on the same dataset, apply Bonferroni or Benjamini-Hochberg correction.
  • Always report both uncorrected and corrected p-values.
  • State the correction method used.
Stratified & Ordinal-Trend Reporting
  • Strata disjointness gate (before any ordinal trend test). Before running a Cochran-Armitage trend test (or any analysis that treats tiers as an ordered partition), assert the strata are mutually exclusive and exhaustive: sum(n per stratum) == unique N and sum(events per stratum) == total events. A trend test on overlapping or non-exhaustive strata is invalid. Emit the per-stratum N/event table and the reconciliation in the output (this is the analysis-side mirror of /self-review check_cohort_arithmetic.py PARTITION_OVERLAP).
  • Secondary stratum-HR validation checklist. Every secondary stratum hazard/odds ratio must be reported with (a) its reference contrast (which category is the referent), (b) the event count in each stratum, and (c) a sparse-stratum caveat when any stratum has a low event count (a rule of thumb: < 10 events makes the estimate unstable). A bare "HR 1.55 in lean participants" without the referent and the events is uninterpretable.
  • Proportion CI lower-bound clamp. Clamp every proportion confidence-interval lowe
