"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."

"Comprehensive Meta‐Analysis is an indispensable tool for efficient problem solving in meta‐analyses.

Comprehensive Meta‐Analysis is extremely easy to use and understand and it is a terrific product."
