Comprehensive Meta-Analysis

Comprehensive Meta-Analysis (CMA) is a powerful computer program for meta-analysis. The program combines ease of use with a wide array of computational options and sophisticated graphics.


"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."

Professor Juan Botella - Autonomous University of Madrid


"I am an advanced graduate student in clinical psychology, and CMA software was integrated into a meta‐analysis course I recently took. I feel very fortunate to have been trained in meta‐analyses at a time when we have this software because CMA is easy and, I dare say, fun to use. Rather than spending countless hours computing my own effect sizes and creating syntax, the program did it for me, which allowed me to spend my time really looking at the data, both graphically and numerically. I bought CMA for myself and would recommend it to anyone looking to learn the art of meta‐analysis."
