"Comprehensive Meta‐Analysis has been the perfect tool for all of my meta‐analysis needs. From calculating effect sizes to examining moderator effects to testing publication bias to building visually appealing forest plots, this program has it all. Its simplicity and straightforward design makes it easy to use for those just learning this data analysis technique. Additionally, with all that is included, this program is also great for those wishing to run more sophisticated analyses."

"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."
