Abstract

Aim This study evaluated the bias and accuracy of the CKD‐EPI/CKiD and EKFC equations compared with the reference exogenous tracer‐based assessment of glomerular filtration rate (GFR) in adult and pediatric patients according to their renal transplant status.
Methods We assessed the bias and P30 accuracy of the CKD‐EPI/CKiD and EKFC equations compared with iohexol‐based GFR measurement.
