2. While this interpretation of I-squared is ubiquitous, it is nevertheless a fundamental mistake. I-squared does not tell us how much the effect size varies.

3. The statistic that does tell us how much the effect size varies is the prediction interval.

1. The vast majority of meta-analyses published in the fields of medicine and epidemiology use the I-squared statistic to quantify the amount of heterogeneity.
