In the original article, there was a mistake in Figure 5 as published. There was a mistake in the generation of this figure, which may make this figure confusing. Some studies were unintentionally unchecked by us when generating forest plot by software Review Manager, resulting in the effect estimates and confidence intervals not being shown. Correspondingly, there are no blocks at the point estimates of intervention effect and horizontal lines of these studies in the forest plot. The corrected Figure 5 appears below.
