"Comprehensive Meta‐Analysis v.2 is the definitive leading software for computing, presenting and analysing results of meta‐analyses. The programme provides beginners as well as advanced researchers meta‐analysis opportunities, unmatched by competing programmes. Computing effect sizes, combining across various types of outcomes, conducting moderators analyses, and presenting these rather complex analyses in less than five stages, could not have been more user‐friendly."

"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."
