SGLT-2 inhibitors have not been evaluated in patients with stage 5 CKD (CKD 5; eGFR, ≤15 mL/minute/1.73 m2). Investigators in Taiwan retrospectively assessed 5 years of outcome data for nearly 48,000 patients with type 2 diabetes and CKD 5 — half of patients had newly initiated SGLT-2 inhibitors, and half were not taking these drugs.

compared with no SGLT2i use, SGLT2i use was associated with lower risks for dialysis (hazard ratio [HR], 0.34 [95% CI, 0.27 to 0.43]), hospitalization for heart failure (HR, 0.80 [CI, 0.73 to 0.86]), AMI (HR, 0.61 [CI, 0.52 to 0.73]), DKA (HR, 0.78 [CI, 0.71 to 0.85]), and AKI (HR, 0.80 [CI, 0.70 to 0.90]), but there was no difference in the risk for all-cause mortality (HR, 1.11 [CI, 0.99 to 1.24]).    So almost higher rates of mortality if you are betting man with 95% confidence
