"Your software is very convenient and useful for systematic reviewers. I used this software to conduct Cochrane systematic review and also helped several postgraduates at University of Ottawa for their research on environmental toxicology and epidemiology. Their manuscripts were all accepted by the internal peer‐reviewed journals."

"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."
