DKD was defined as a urine albumin to creatinine ratio (ACR) ≥300 mg/g or estimated GFR <60 mL/min per 1.73 m2 and ACR ≥30 mg/g. Longstanding diabetes with no kidney disease were individuals with ≥30 years of type 1 diabetes, estimated GFR >90 mL/min per 1.73 m2, and ACR <300 mg/g. NA, hemoglobin A1c levels were not available for the subgroup with new‐onset diabetes.
