1 Meta-regression is a tool used in meta-analysis to examine the impact of moderator variables on study effect size using regression-based techniques. 2  Meta-regression is more effective at this task than are standard regression techniques.
What is a meta-analysis? Meta-analysis is the statistical procedure for combining data from multiple studies. When the treatment effect (or effect size) is consistent from one study to the next, meta-analysis can be used to identify this common effect. When the effect varies from one study to the next, meta-analysis may be used to identify the reason for the variation. Why perform a meta-analysis? Decisions about the utility of an intervention or the validity of a hypothesis cannot be based on the results of a single study, because results typically vary from one study to the next.
