"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 experience with Comprehensive Meta‐analysis is highly positive. The spreadsheet interfaces for data entry are very intuitive. They handle an astonishing wide array of indices and formats for effect sizes, including the possibility of entering them in the spreadsheet by copy‐and‐paste. The exploratory phase is easily performed thanks to a variety of facilities, as cumulative meta‐analysis, sensitivity analysis by the “one‐study‐removed” procedure, and subgroup analysis, among others. It covers all basic fixed and random effect models and provides high‐quality graphical outputs for reports. The tutorial and the manual are really helpful and friendly. In short, Comprehensive Meta‐analysis is my favorite tool both for performing and teaching meta‐analysis."
