"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."

"While I was looking for a computer program for meta‐analysis, I did a thorough search and compared all available programs I located. I decided to use CMA because of its versatility and authoritativeness. It allows me to code data of various formats and conduct all kinds of analysis – Q tests, meta‐regression, sensitivity analysis, etc. It also provides results associated with both the fixed‐effects and randomeffects models. Furthermore, the program is developed by a team of leading scholars in meta‐analysis. I feel lucky to be able to find a program through which I can draw on the expertise of so many outstanding experts."
