Comprehensive Meta-Analysis

Comprehensive Meta-Analysis 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 using Comprehensive Meta-Analysis for more than 3 years and have finished a dozen meta-analysis with this software. The biggest advantage is easy to perform and manage the analysis. Studies can be added or removed from the analysis without modifying the data. There are a variety of effect size measures, including treatment difference, odds ratios, rate differences, correlations, etc. The diagnosis and transformation of the effect size is just one click away. The high-quality forest plot and comprehensive meta-regression distinguished this software from others.”

“I can confirm that comprehensive meta-analysis is a very valuable tool for analyzing data. In one of my most important publications the use of forest plots constructed with Comprehensive Meta-analysis has contributed to the success of this article. As a clinician my statistical background is not as strong as I would like it to be. However, using CMA is very straightforward and I was able to astonish my epidemiologist co-author. I can recommend Comprehensive Meta-Analysis to any clinical researcher.”
