"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."

Peter C. Gøtzsche - Professor, Director, MD, DrMedSci, MSc, Nordic Cochrane Centre, Copenhagen, Denmark

"Comprehensive Meta‐Analysis (CMA) is a must‐have tool for academic instructors, researchers, and statisticians alike. Developed by a strong team of highly recognized experts in the field, CMA meets all of your meta‐analysis needs and is easy to teach and easy to use. I would not attempt to ever conduct another meta‐analysis without using the CMA program, for the difference is between heaven and earth!"
