Scatter plots of (A) diversity (\(\widehat{D}\) 2) versus estimated between-study variance (\(\widehat{\tau }\) 2) and (B) required information size (\(\widehat{RIS}\)) versus estimated between-study variance (\(\widehat{\tau }\) 2), for smaller meta-analysis without significant heterogeneity, smaller meta-analysis with significant heterogeneity, larger meta-analysis without significant heterogeneity, and larger meta-analysis with significant heterogeneity.
