"We bought the CMA software for professional perpetual version at the beginning of this year, and we have used it to do meta-analyses for several studies and trained the postgraduate students already. The friendly spreadsheet, easy-understandable dialog, not programming and modifiable output style make use of the software to do a meta-analysis convenient. The most fabulous point is that it can extend the traditional comparison of two groups to estimation of effect size in one group and generic point estimates. In summary, this software is an efficient and user-friendly tool for scientists to do a study related to meta-analysis."

"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."
