"I've been using different versions of the comprehensive meta‐analysis software over many years for my research. Each version improved significantly, added new and important features, and made the visual outcomes easier to comprehend and present. One such improvement, for example, was the addition of moderater analysis for both categorical and continuous variables. It provides an easily understood menu that guides the user toward a correct statistical analysis. I also find the manual very useful and supportive, recommend it to my graduate students to use it for self‐teaching learning."

"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."
