4. Kidney function
Two RCTs assessed kidney function using eGFR. These studies included 241 participants and the random-effects model was used in this analysis owing to the high heterogeneity (I²=66%, p=0.08). Results of this meta-analysis found no significant group differences on eGFR, with the pooled MD = -0.44(95% CI: -8.32 to 7.43, p=0.91)(Figure 8).
