"The distinguishing feature of the Comprehensive Meta‐Analysis Software Programme from the other Meta‐Analysis Software Programmes is to be most practical and to be understandable easily. While using the programme the only thing should be done is to enter the necessary data into the data sheet and to click on the relevant buttons. That's all. No need to calculate the statistical formulas by hand to reach the effect sizes, anymore. I would like to send my special thanks to you and your team from Ankara University, Ankara‐Turkey, Sevgi Guney, MSc in ClinPsych, MAPS"

"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."
