Power of FE, RE2 and our new RE2C method for the meta-analysis of independent statistics. Assuming the statistics are independent, we simulated various effect size distributions with differing amounts of heterogeneity. We considered the scenario that RE2 or RE2C is additionally applied to FE while accounting for multiple testing. The power of RE2 and RE2C are shown as two-color stacked bars, where we colored the proportion identified by FE as significant in light grey and the proportion that RE2/RE2C additionally identified as significant in dark grey
