Figure 4: Bland-Altman plot of the mean serum amikacin ( -axis) trough concentrations (a) and peak concentrations (b) versus difference ( -axis) between predicted and observed amikacin concentrations. The solid line represents the mean difference; the dashed lines represent the limits of agreement (mean difference ±2 SD difference).
