Figure 26 is a forest plot. Standardized mean differences were reported or calculated for four short-term studies, with a pooled standardized mean difference of −0.73 (95% confidence interval −1.84 to 0.36) and an overall I-squared value of 95.1%. Standardized mean difference was reported or calculated for one intermediate-term study (0.14, 95% confidence interval −0.12 to 0.40). Standardized mean difference was reported or calculated for one long-term study (−0.39, 95% confidence interval −0.74 to −0.03).
