# Statistical analysis plan: outline

Illustrative document structure. This is a blank planning aid, not a completed client deliverable or an analysis recommendation for a particular dataset.

1. Project title, version, date, and responsible reviewers.
2. Research question, objectives, and study design.
3. Data source, setting, population, and relevant permissions.
4. Analysis population, inclusion and exclusion criteria.
5. Outcomes, exposures, covariates, and operational definitions.
6. Data-quality checks and documented cleaning decisions.
7. Descriptive analysis.
8. Primary analysis and its rationale.
9. Assumptions and planned diagnostic checks.
10. Missing-data approach and its justification.
11. Secondary, subgroup, and sensitivity analyses, where appropriate.
12. Planned tables and figures.
13. Reproducibility, software, and version control.
14. Review responsibilities, interpretation, and limitations.
15. Deviations from the agreed plan and their rationale.

Each project requires a qualified reviewer to decide which sections and methods apply. No statistical results, client outcomes, or specific software capability are implied by this outline.
