"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."

"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."
