Fig. 2. Distribution of eGFR categories and CKD stages according to eGFR equation in the Korean general population. Data from the KNHANES 2019–2020. eGFR (mL/min/1.73 m²) categories: G3a, 59–45; G3b, 44–30; G4, 29–15; G5, <15. CKD was defined as an eGFR <60 mL/min/1.73 m² or urinary albumin-to-creatinine ratio >30 mg/g. For details, see Supplemental Data Fig. S1 and Supplemental Table S2. *P<0.05, ^†P<0.001, ‡not significant.
