"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checks of meta‐analytic outcomes such as trim‐and‐fill and other state‐of‐the‐art ways to test the influence of unpublished papers.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."

"The CMA program has been invaluable to us and greatly sped up the generation of a number of metaanalyses that we have conducted. It is actually user‐friendly (a compliment I rarely make!), has all the needed key features and is a pleasure to use. Not only that, Dr. Borentein was very helpful and responsive when we needed help. Thank you!"
