Abstract: The metaan command performs a meta-analysis on a set of studies and calculates the overall effect and a confidence interval for the effect. The command also displays various heterogeneity measures: Cochrane's Q, I-squared, H-squared and the between-study variance estimate. Cochrane's Q is the same across all methods, but the between-study variance estimate (and hence I-squared and H-squared) can vary between the dl and ml methods. Only one method option must be selected. For calculating the effects and variance of the effects, for a group of studies, from various statistical parameters please see metaeff on this archive.
