Fig. 2. Comparison between estimated glomerular filtration rate (eGFR) and measured GFR (mGFR). (A and B) Creatinine-based Chronic Kidney Disease Epidemiology Collaboration (CKD-EPIcr) equation; (C and D) Asian CKD-EPI equation; (E and F) Revised Lund–Malmö (Revised LM) equation; (G and H) Full-age spectrum (FAS) equation; (I and J) Korean FAS equation. The gray line in the scatter plot represents the identical line. Solid and dashed black lines in the Bland–Altman plot represent the mean and 95% limits of agreement (LoA) of bias, respectively.
