eGFR, estimated glomerular filtration rate; CKD, chronic kidney disease.

^aLow eGFR was defined as eGFR <60 ml/min/1.73 m².

^bCKD stage 1: eGFR ≥ 90 ml/min/1.73 m²; stage 2: 60 ml/min/1.73 m² ≤ eGFR <90 ml/min/1.73 m²; stage 3: 30 ml/min/1.73 m² ≤ eGFR <60 ml/min/1.73 m²; stage 4: 15 ml/min/1.73 m² ≤ eGFR <30 ml/min/1.73 m²; stage 5: eGFR <15 ml/min/1.73 m².
