Participants are classified according to their KDIGO GFR category according to the GFR estimation following the CKD-EPI 2009 and the EKFC equation, separated for ‘events’ and ‘no events’. All those written in bold are reclassified to a more suitable category according to their ‘event—no event status’, all those written in italic are reclassified falsely according to their ‘event—no event status’. G1: eGFR ≥90 ml/min/1.73 m2; G2: eGFR 60–89 ml/min/1.73 m2; G3a: eGFR 45–59 ml/min/1.73 m2; G3b: 30–44 ml/min/1.73 m2; G4: eGFR 15–29 ml/min/1.73 m2; G5: eGFR <15 ml/min/1.73 m2. CI: confidence interval; eGFR: estimated glomerular filtration rate; NRI: net reclassification improvement.
