To compute a pooled effect size from multiple independent studies, use a fixed or random-effects meta-analysis model like DerSimonian-Laird. This aggregates diverse outcome types such as SMD, MD, OR, or RR into a single reproducible pooled estimate.

Heterogeneity assessment in meta-analysis evaluates variation across combined studies using I², Q, and τ² statistics. You need it when synthesizing evidence from independent studies to ensure the pooled effect size is valid and not skewed by outliers.

Yes, you can use random-effects meta-analysis for systematic reviews with diverse outcome types. It supports outcomes like SMD, MD, OR, or RR, and provides structured, reproducible reporting required for guideline development.

The best way to detect bias in multi-study data integration is by generating funnel plots. This diagnostic visualization helps identify potential publication biases during evidence synthesis, ensuring the pooled estimate is reliable.

To visualize effect sizes across studies for reproducible reporting, generate forest plots. This diagnostic display plots individual study effects and the pooled estimate, satisfying standard requirements for systematic reviews.

If your meta-analysis shows high heterogeneity, interpret it using the provided I², Q, and τ² statistics. High values indicate substantial variation across studies, suggesting the pooled effect size may not represent a uniform effect.
