"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."

"CMA is very easy to use. That’s partly because of the manual and tutorial which take you through the analysis step by step. It’s also extremely versatile in terms of the type of input data it will accept (which is really valuable because with a meta‐analysis you have to take what data you can get). The output is comprehensive enough to permit you to interpret your effects, not merely report them."
