MetaWin first published in 1997, allows the user to easily carry out all common meta-analysis calculations on independent studies from a wide variety of disciplines, including medicine, ecology, and the social sciences, compare mean effect sizes and confidence limits of different classes of studies with the click of a mouse, and examine the results of within- and between-group heterogeneity using parametric methods as well as resampling tests. The program allows users to refine their analyses by choosing which specific groups and individual studies from their data sets they wish to analyze or eliminate. In addition, Version 2.0 of MetaWin allows users to calculate any of six different effect sizes from their data, and can be used for a variety of statistical meta-analytic models. MetaWin runs on IBM-compatible computers running Windows 95/98/NT, with a minimum 8MB of RAM. A comprehensive 128 page manual is included with the program, which includes chapters describing the statistical theory of meta-analysis, an explanation of effect sizes and meta-analytic summary model calculations, and a description of how these calculations may be performed in MetaWin. Cost for a single user is $150 (discounts available for students and version 1.0 users).

A new Software Update for MetaWin was released on February 12, 2007.
