Note: Values are given as n (row percentage). eGFRcr categories expressed in mL/min/1.73 m2. Italic indicates reclassification to higher eGFR categories using eGFRcys compared to eGFRcr, bold indicates reclassification to lower eGFR categories using eGFRcys compared to eGFRcr.
eGFRcr, creatinine-based estimated glomerular filtration rate; eGFRcys, cystatin C–based estimated glomerular filtration rate;
