Use when comparing an exposure-outcome association across countries with parallel national surveys (KNHANES, NHANES, CHNS). Harmonizes variables, runs parallel weighted analyses and builds comparison tables for 2-country (KR+US) or 3-country (KR+US+CN) designs.
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
# Cross-National Comparison Study Skill ## Inputs 1. **Research question**: exposure → outcome association to compare across countries 2. **Korean data path**: KNHANES CSV file 3. **US data path**: NHANES CSV directory (multiple tables to merge) 4. **Harmonization table** (optional): CSV mapping variables across surveys - Default: `/replicate-study`'s `references/harmonization_knhanes_nhanes.csv` ## Reference Files - `/write-paper`'s `references/paper_types/cross_national.md` — writing template - `/analyze-stats`'s `references/analysis_guides/survey_weighted.md` — survey-weighted analysis guide - `references/chns_coding.md` — CHNS files, merge keys, coding and warnings; read it when the design includes China (3-country design) - `references/additional_variables.md` — asthma, sleep, physical activity, diet, treatment and non-HDL-cholesterol coding, plus composite-score (LE8) warnings; read it when the study uses any of them ## Workflow ### Phase 1: Study Definition 1. Confirm research question: Exposure → Outcome 2. Define variable coding for both countries: - Exposure: PHQ-9, BMI category, smoking, etc. - Outcome: diabetes, hypertension, mortality, etc. …

How to install
mdr add aperivue/medsci-skills/cross-national@sha256:cd1659f013b94259The line at the top of this page pins the label git:20261002.4215513, 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.
