"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checks of meta‐analytic outcomes such as trim‐and‐fill and other state‐of‐the‐art ways to test the influence of unpublished papers.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 am impressed with the ease or simplicity of the Comprehensive Meta‐Analysis, not only in data entry but also the data generated. Unlike some of the free software available for meta‐analysis, I found the Comprehensive Meta‐Analysis user‐friendly, generating clear graphs and effect sizes. I took a long time to work out some of the free software available by some of my colleagues and found them very userunfriendly, confusing, and the graphs generated not easy on the eye. After chancing on Comprehensive Meta‐Analysis during a Google search and having a go at it during the free trial, I was keen to get my hands on it and have recommended it to some of colleagues. It is definitely worth getting it as it makes meta‐analysis non‐daunting and non‐scary especially for students pursuing their Masters or PhDs."
