Abbreviations: CKD chronic kidney disease
^aCKD G stages according to KDIGO based on eGFR_CKD-EPI; G1 eGFR ≥90 ml/min/1.73m²; G2 60–89, G3a 45–59, G3b 30–44; G4 15–29, G5 < 15 or renal replacement therapy
^bDefinition based on eGFR_CKD-EPI and urinary albumin/creatinine (ACR) ratio; KDIGO-stages G1A1, G1A2 and G2A1 considered as normal kidney function, whereas G1A3, G2A2, G2A3 and more severe G-stages are considered as chronic kidney disease (CKD) (see Methods)
