3.5 Publication Bias Analysis sheet
Publication bias analysis is not a core meta-analysis feature and for some of the methods rather
strong assumptions apply, which means they should be used with caution (see Hak et al., 2015a).
Multiple procedures or statistics regarding publication bias analysis are provided by Meta-Essentials:
funnel plot, Egger regression, Begg and Mazumdar's rank correlation test, standardized residual
histogram, Galbraith plot, normal quantile plot, and several failsafe-N tests. They can be accessed by
clicking on the regarding tab, as shown in Figure 17.
