"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."

"I recently used Comprehensive Meta‐Analysis on a large and complex data set involving several different outcome variables, several different research designs, and hundreds of effect sizes. I found the program easy to use and very powerful. Moderator analyses were easy to conduct, as were examinations of potential publication/selection biases. The user interface is intuitive and easy to navigate. It is a wonderful tool!"
