"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."

"Our group has recently begun to conduct meta‐analyses within our area of research, i.e. psychooncology and health psychology, and we have found CMA extremely useful. CMA distinguishes itself from other available meta‐analysis software by the various options to explore and adjust for possible publication bias, as well as by providing several options to explore possible moderators, not only categorical but also continuous. We encourage our PhD students to conduct quantitative systematic reviews as a part of their dissertation whenever possible. The clear menu‐driven approach of CMA makes it easy to use for beginners, so that they can focus their energy on the analytical aspects of metaanalysis, rather than on the technical issues of using the software."
