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).
