"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."

"Thank you for developing Comprehensive Meta‐Analysis. It is by far the best tool available for today’s meta‐analytic researcher. It provides flexibility for all possible types of data, it produces great colorful graphical displays, and the product support is unmatched! I have used a number of different programs for conducting meta‐analytic research over the last ten years, and CMA is the only product I recommend to my students and colleagues."
