"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."

"Comprehensive Meta‐Analysis (CMA) is a must‐have tool for academic instructors, researchers, and statisticians alike. Developed by a strong team of highly recognized experts in the field, CMA meets all of your meta‐analysis needs and is easy to teach and easy to use. I would not attempt to ever conduct another meta‐analysis without using the CMA program, for the difference is between heaven and earth!"
