Core Tip

Core Tip: In the study, we can see in the type 2 diabetes mellitus results and pooled analyses, the authors said that “the low heterogeneity was graphically observable, also looking at the Galbraith and Funnel plots (Figure 3A and B)”. This is mistake and funnel plot should only be used to check for the publication bias. And in order to test for publication bias for this study, quantitative Begg’s test and Egger test were recommended, because the number of inclusion studies are less than 10.
