"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 so easy to use that a clinician feels absolutely comfortable with it. You only need to have the results from individual studies and follow instructions: you will have calculations and graphs in a way that you can easily interpret. With this software meta‐analysis is not arcane any more: if you can read papers based on this statistical technique you will be able to write them as well."
