"My colleagues and I thought that the software is really easy to use. My students were also very satisfied. The task of calculating effect sizes was easy to understand, even for people without advanced knowledge in statistics. The program has numerous options for data entry, calculation of effect sizes, and tests for heterogeneity and publication bias, and facilitates the presentation to a comprehensive meta‐analytic project. Technical and other support from the company was available immediately."

"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!"
