This workshop will cover the use of Stata to perform meta-analysis. Meta-analysis is a statistical technique for combining the results from several similar studies. The workshop will provide a brief introduction to meta-analysis and will demonstrate how to perform meta-analysis in Stata 19. Stata’s meta command offers full support for meta-analysis from computing various effect sizes and producing basic meta-analytic summary and forest plots to accounting for between-study heterogeneity and potential publication bias. Several case studies demonstrating how to conduct a meta-analysis within Stata will be provided. These examples will focus on the interpretation of meta-analysis, meta-regression and its postestimation features, subgroup analysis, small-study effect and publication bias, and various types of forest, funnel, and other plots. No prior knowledge of Stata is required, but basic familiarity with meta-analysis will prove useful. [Read more ...]
