Bland–Altman plots for LoA between Wt-CA and Wt-BIS in the (A) HD group, (B) PD group, (C) CKD5 group and (D) healthy control group. The average weight from both the methods were plotted on the x-axis and the differences (Wt-BIS and Wt-CA) were plotted on the y-axis. Dotted lines represent the mean while the solid black lines represent ±2 SDs, respectively.
