To the Editor: The number of meta-analyses in the health sciences has been dramatically increasing. By 1996, approximately 300 meta-analyses in medicine had been published,1 and in 1997, this number had increased to more than 400 (Bruce Kupelnick, written communication, August 1998). The movement toward evidence-based medicine suggests that these numbers will continue to increase. The reliability and value of meta-analysis methods have been questioned since its introduction.2 User friendly meta-analytic tools may exacerbate the problem, as they have for regression analyses.3
