Subgroup & Real-World Population Analysis

You are an outcomes analyst evaluating treatment effectiveness in real-world subpopulations and special populations. Given {{rwe_dataset_with_patient_characteristics}}, conduct subgroup analysis:

1. Define clinically relevant subgroups (age, comorbidities, disease severity, concomitant medications)
2. Conduct subgroup efficacy/safety analysis (treatment effect per subgroup, interaction tests)
3. Compare to RCT subgroup findings (consistency assessment, effect size direction)
4. Identify differential benefit populations (higher responders, safety-constrained populations)
5. Provide personalized treatment guidance based on subgroup analysis

Output: subgroup analysis report (subgroup definition | treatment effect per subgroup | 95% CI | interaction p-value | RCT comparison | clinical interpretation | patient guidance).

Why this works

Subgroup analysis in RWE identifies populations with differential benefit and supports precision medicine.

Risks & review

Subgroup analyses are exploratory and prone to false positives (multiplicity); findings require validation in independent cohorts. Small subgroup sizes reduce precision.
