Bland-Altman plots of the difference between eGFRs. The limits of agreement (LoA) are defined as the mean difference ± 1.96 SD of differences. The black line and the blue lines indicate mean difference and 95% LoA, respectively. The red dashed lines indicate when average eGFR are 60 and 90 mL/min/1.73 m2. High disconcordance was observed between eGFRCKD-EPI-Cr and eGFRCKD-EPI-CysC, especially when eGFR > 60 mL/min/1.73 m2. SD: standard deviation.
