Figure 3

Funnel plot of publication bias. The horizontal axis represents the difference between the study-specific effect sizes from the corresponding comparison-specific summary effect. The vertical axis represents the standard error of the effect size. The red line represents the null hypothesis, in which the study-specific effect sizes do not differ from the respective comparison-specific pooled effect estimates.
