Horizontal bar graph for NNT. Numbers were derived from the pooled standardized mean difference (SMD) effect size for each meta-analysis and based on a random-effects model in which results were statistically significant (p ≤ 0.05) with non-overlapping 95% confidence intervals. Results were not pooled across all analyses because some of the results included the same studies.
