Introduction to Meta-analysis in Stata

February 27, 2023 @ 1:00 pm - 4:00 pm

Meta-analysis is the synthesis of results from previous studies.  It is used to increase power, obtain a better estimate of an effect size, and sometimes to resolve conflicting conclusions in the literature.  In this workshop, we will discuss how the data for a meta-analysis are collected and organized, as well as how such data are analyzed and graphed.  We will also discuss some of the limitations meta-analysis and what should be included in a meta-analysis for publication.
