SGLT2 inhibition was not associated with a significant change in eGFR in general (weighted mean difference (WMD), −0.33 ml/min per 1.73 m2, 95% CI [−0.90 to 0.23]) or in patients with chronic kidney disease (CKD) (WMD −0.78 ml/min per 1.73 m2, 95% CI [−2.52 to 0.97]). This evidence concerns the gene SLC5A2 and chronic kidney disease.
