"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."

"I recently used Comprehensive Meta‐Analysis on a large and complex data set involving several different outcome variables, several different research designs, and hundreds of effect sizes. I found the program easy to use and very powerful. Moderator analyses were easy to conduct, as were examinations of potential publication/selection biases. The user interface is intuitive and easy to navigate. It is a wonderful tool!"
