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.


"I have been a satisfied user of Comprehensive Meta‐Analysis software for about two years. I find the software is easy to use and offers an extensive range of options for analysis. I like being able to toggle between fixed and random effects, and seeing the difference(s) between the two. I also find that the ability to evaluate symmetrical confidence intervals, and have non‐symmetry flagged, is a major advantage to the software. The automatic generation of funnel plots, which do not exist as an option in many scientific graphing packages, is particularly of value when discussing bias."

"We had no knowledge on meta‐analyses and were somewhat confused by the number of programs available. Most of them were not easy to use, not insightful and required a priori knowledge of metaanalyses statistics. There was one exception: Comprehensive Meta‐analysis. We downloaded the software and went through the easy‐to‐use tutorial. Within an hour we were performing our own metaanalysis! Our analysis was verified by our statistical department with excellent results, giving us further confidence to continue our analysis and resulting in an excellent paper in the top journal on pain research: Niesters et al., Do Sex Differences Exist in Opioid Analgesia? A Systematic Review and Meta‐ Analysis of Human Experimental and Clinical Studies. Pain, 2010, in press, doi:10.1016/j.pain.2010.06.012."
