"We had no knowledge on meta‐analyses and were somewhat confused by the number of programs available. Most of them were not easy to use, not insightful and required a priori knowledge of metaanalyses statistics. There was one exception: Comprehensive Meta‐analysis. We downloaded the software and went through the easy‐to‐use tutorial. Within an hour we were performing our own metaanalysis! Our analysis was verified by our statistical department with excellent results, giving us further confidence to continue our analysis and resulting in an excellent paper in the top journal on pain research: Niesters et al., Do Sex Differences Exist in Opioid Analgesia? A Systematic Review and Meta‐ Analysis of Human Experimental and Clinical Studies. Pain, 2010, in press, doi:10.1016/j.pain.2010.06.012."

"As a first‐year graduate student with minimal knowledge of meta‐analysis at the time, I found Comprehensive Meta‐Analysis to be an incredibly user‐friendly program. I began using Comprehensive Meta‐Analysis while reading Lipsey & Wilson's (2001) Practical Meta‐Analysis and found it easy to transition from the conceptual and practical issues discussed in their text to the procedures available in your program. My mentor and I continue to use your program as we prepare my Master's thesis for publication, and our use of this software has undoubtedly facilitated our progress. Best of luck with the future development of Comprehensive Meta‐Analysis and with your ongoing scholarship."
