Use when one validated cohort analysis must be repeated across many exposure/outcome pairs. Generates one R/Python script per combination from a single methodology template, changing only the variables, and aggregates the results into a summary matrix.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Batch Cohort Analysis Skill

Generate one analysis script per exposure/outcome combination from a single validated methodology
template; only the variables change between scripts.

## Inputs

1. **Database path(s)**: CSV/SAS data files (KNHANES, NHANES, NHIS, or any cleaned cohort)
2. **Methodology template**: One of:
   - Path to a validated R/Python analysis script (from /replicate-study or /cross-national)
   - A paper type template name: `nhis_cohort`, `cross_national`, `survey_weighted`
   - A source paper to extract methodology from (falls back to /replicate-study Phase 1)
3. **Combination spec**: A list of exposure/outcome pairs, provided as:
   - Inline list: `exposures: [depression, obesity, smoking]; outcomes: [diabetes, hypertension, CVD]`
   - CSV file with columns: `exposure`, `outcome`, (optional) `subgroup_vars`
   - `"all"` keyword: generates all pairwise combinations from the lists

### Optional Inputs

- **Covariate set**: Fixed covariate list for all analyses (default: use template's set)
- **Subgroup variables**: Variables to stratify by (default: sex, age group)

How to install

The exact contents, by fingerprint
mdr add aperivue/medsci-skills/batch-cohort@sha256:8f9b00b4e83b4261

The line at the top of this page pins the label git:20261004.5b44a65, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
