Figure 1 Difference plot. Modified Bland–Altman difference plot between (a) creatinine clearance-I (Ccr-I, ml/min), and (b) creatinine clearance-II (Ccr-II, ml/min per 1.73 m2) and estimated GFR (eGFR) against body surface area (BSA) in patients with Ccr>60 ml/min per 1.73 m2 (n=160), and same plots in patients with Ccr<60 ml/min per 1.73 m2 (n=93), (c) and (d), respectively. Correlation coefficients of the differences between (a) Ccr-I, (b) Ccr-II, and eGFR against BSA were r=0.640 (P<0.001) and r=0.286 (P<0.001), respectively. Correlation coefficients of the differences between (c) Ccr-I, (d) Ccr-II, and eGFR against BSA were r=0.290 (P=0.005) and r=0.068 (P=0.516), respectively.
