Figure 4 is a forest plot. Standardized mean differences were reported or calculated for 11 short-term studies, with a pooled standardized mean difference of −0.51 (95% confidence interval −0.98 to −0.08) and an overall I-squared value of 88.1%. Standardized mean differences were reported or calculated for five intermediate-term studies, with a pooled standardized mean difference of −0.17 (95% confidence interval −0.39 to 0.02) and an overall I-squared value of 0%. Standardized mean difference was reported or calculated for one long-term study (0, 95% confidence interval −0.38 to 0.38).
