"Even in its earliest versions, Comprehensive Meta‐Analysis was easy to use. More importantly, Michael Borenstein and his colleagues were readily available to assist with the few questions I had about the software. For beginners in meta‐analysis and for seasoned researchers, I highly recommend this program. You will not be disappointed."

"I am a PhD Candidate and used your software to successfully complete my Master's thesis. I find the CMA software to be very user‐friendly; it was easy to learn how to use and has an excellent selection of options for analysis. I also find the customer support to be very helpful and timely. I would and have recommended the software to others."
