  1. Mean (standard deviation; SD) or median (interquartile range; IQR) unless otherwise specified. CKD-EPI: Chronic Kidney Disease Epidemiology Collaboration; eGFRcr: estimated GFR by creatinine; eGFRcys: estimated GFR by cystatin C; eGFRcr-cys: estimated GFR by creatinine and cystatin C; EKFC: European Kidney Function Consortium; mGFR: measured glomerular filtration rate (GFR) by single-point plasma clearance of iohexol.
