Comprehensive Meta-Analysis

software image

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.


"CMA has been a huge asset in my research on motivation and self‐regulation. I have used this software to conduct multiple meta‐analyses, each requiring different and multiple formats of effect size. CMA surpassed my needs and expectations every time. The software is really "comprehensive" yet exceptionally user‐friendly. Fellows and students have learned to use it in just one sitting. I highly recommend CMA to any researcher wishing to conduct meta‐analysis in a highly effective and efficient manner."

"Although my centre develops the statistical software the whole Cochrane Collaboration uses for its systematic reviews and meta‐analyses (Review Manager), I have often used Comprehensive Meta‐ Analysis for my own research projects, as it is easy to import data from Excel, to use effect modifiers, and also because it allows meta‐regression and produces bubble graphs that are easy to work with in Word or PowerPoint."
