"Comprehensive Meta‐Analysis is a fabulous program for research synthesis, combining ease of use with advanced features not available in standard statistical packages or competing stand‐alone products. The program is ideal for independent analysis or reanalyzing data from another published review (including Cochrane reviews) to explore subgroups, moderator variables, and clinically relevant measures of effect size. Forest and funnel plots can be easily created and customized for publicationquality graphics. As editor in chief of Otolaryngology – Head and Neck Surgery, I find the program indispensable for preparing a quarterly installment, The Cochrane Corner, which highlights a relevant Cochrane review and provides expert commentary to aid clinicians in applying and understanding the results. I strongly recommend this program to novice and experienced meta‐analysts alike."

"CMA is a very useful and friendly software that has being used both as an auxiliary tool for my papers preparation, and as the program elected for the analysis that I usually do with my students in order to train them in this field of meta‐analysis. In brief, this is a very well‐conceived statistical analysis software, useful for trainees in statistical analysis as well as for senior researchers."
