"CMA is a formidable tool for conducting sophisticated meta‐analyses in the domain of cognitive and behavioral sciences. As an early adapter of CMA I am still amazed about its flexibility in data storing, data processing, and its many options for validity checks of meta‐analytic outcomes such as trim‐and‐fill and other state‐of‐the‐art ways to test the influence of unpublished papers. The flexibility of CMA to exchange data with Excel, SPSS, and other statistical software is a major asset. I also taught courses on meta‐analysis with the student version of CMA available for the graduate students, and it has been a real success as CMA makes meta‐analysis transparent as well as motivating for students with a basic training in statistics."

"I have now used Comprehensive Meta‐Analysis in five meta‐analyses and highly recommend it. Its structure and accompanying resources particularly assist researchers with clinical rather than statistical backgrounds to avoid important errors in data entry and analysis. Comprehensive Meta‐Analysis enables meta‐analysis methods recommended by leading statisticians and meta‐analysts to be used by researchers internationally."
