"Comprehensive Meta‐Analysis is the premier program for conducting meta‐ analyses. It has incredible flexibility in including many different types of effect sizes and in converting between them in a single analysis. It is extremely user‐friendly and has brilliant graphical capabilities."

David P. Farrington - Institute of Criminology, Cambridge University

"As an NIH funded meta‐analytic researcher, I can honestly say that Comprehensive Meta‐Analysis is currently the most comprehensive stand‐alone software package for conducting high‐quality metaanalyses. I especially like its ease of use, including, but not limited to, the ability to calculate effect sizes from a large array of reported statistics as well as the ability to easily combine results from multiple groups in the same study into one common effect size. In my opinion, this is a “must” purchase for any serious meta‐analyst."
