"Thank you for developing Comprehensive Meta‐Analysis. It is by far the best tool available for today’s meta‐analytic researcher. It provides flexibility for all possible types of data, it produces great colorful graphical displays, and the product support is unmatched! I have used a number of different programs for conducting meta‐analytic research over the last ten years, and CMA is the only product I recommend to my students and colleagues."

"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."
