"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."

"The CMA program has been invaluable to us and greatly sped up the generation of a number of metaanalyses that we have conducted. It is actually user‐friendly (a compliment I rarely make!), has all the needed key features and is a pleasure to use. Not only that, Dr. Borentein was very helpful and responsive when we needed help. Thank you!"
