"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."

"The distinguishing feature of the Comprehensive Meta‐Analysis Software Programme from the other Meta‐Analysis Software Programmes is to be most practical and to be understandable easily. While using the programme the only thing should be done is to enter the necessary data into the data sheet and to click on the relevant buttons. That's all. No need to calculate the statistical formulas by hand to reach the effect sizes, anymore. I would like to send my special thanks to you and your team from Ankara University, Ankara‐Turkey, Sevgi Guney, MSc in ClinPsych, MAPS"
