"Comprehensive Meta‐Analysis is a cutting‐edge tool for researchers who are involved in systematic review and meta‐analysis. It provides methods for analyzing and presenting data that are easy to use and give clear presentations of findings. This is just a fantastic tool! Every serious scholar in this area should have it."

"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."
