How the analysis is checked

Every guide and tool James reviews follows the standard methods set out in the Cochrane Handbook for Systematic Reviews of Interventions and in Borenstein, Hedges, Higgins, and Rothstein, Introduction to Meta-Analysis. The pooling behind our calculators is validated against the metafor package in R and statsmodels in Python, so the numbers line up with what a statistician reproduces by hand. You can read more about how we calculate and check every result.
