"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."

"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!"
