Combine results of multiple studies to estimate an overall effect. Use
forest plots to visualize results. Evaluate study heterogeneity with
subgroup analysis or meta-regression. Use funnel plots and formal tests
to explore publication bias and small-study effects. Assess the impact
of publication bias on results with trim-and-fill analysis. Perform
cumulative meta-analysis. Use the meta suite of commands, or let the
Control Panel interface guide you through your entire meta-analysis.
