Subgroup Analysis Skill

Purpose

Examine whether effects differ across subgroups of participants or studies.

Planning Subgroup Analyses

Pre-Specify:

Which subgroups (age, sex, severity)
Rationale for each
Statistical approach

Limit Number:

Too many = Type I error inflation
Focus on theoretically important
Correct for multiple comparisons

Subgroup Analysis Methods

1. Interaction Tests

Test group × subgroup interaction
More powerful than separate analyses

2. Stratified Analysis

Separate analysis per subgroup
Compare effect sizes

3. Meta-Regression

Continuous moderators
Multiple moderators simultaneously

Interpretation Cautions

Observational Nature:

Subgroups not randomized
Confounding possible
Generate hypotheses, don't confirm

Multiple Testing:

Adjust alpha (Bonferroni)
Or report as exploratory

Example: "Pre-specified subgroup analysis showed larger effects in younger participants (<50 years, d=0.68) versus older (≥50 years, d=0.34), interaction p=.02."
