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 used Comprehensive Meta‐Analysis software within a course on research methods for doctoral students in nursing. With only a 90‐minute introduction, students were ready to begin data entry and to conduct basic analyses. Both they and I were pleased with its intuitive interface and with the clarity of its output. Additionally, Biostat, Inc. has provided excellent support in our efforts to employ the software in a classroom setting."

"One of the hardest things for non‐statisticians conducting meta‐analyses is to figure out how to combine data when the data are in different forms. Using continuous outcome as an example, one study might report before‐and‐after scores, and another might report change scores. Comprehensive Meta‐Analysis allows one to take data in any form and seamlessly converts it so that all the data can be included, or tells the meta‐analyst what additional information is necessary to complete the process. This one aspect of the program can save hours of time for non‐statisticians who are not used to converting data from one format to another."
