"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."

"I've used CMA for years now as a researcher and teacher. It is uncommon to see a program that is so full‐featured yet easy enough to use that you can pick it up in an afternoon. The calculations are spoton and the images are sharp enough for use in publication. I recommend the software to all of my students and colleagues who are performing meta‐analysis."
