Bland-Altman plots for each machine (machines A, B, C, and D) and the reference machine. The Bland-Altman plot shows an agreement within the limits of clinical usefulness, with the mean of differences (bias) always being less than 20%. Specifically, the bias ranged from −3.4 to 7.4 μmol Fe/g, which can be considered negligible values.
