Bland–Altman plots of passive trials 1 and 2 for ${\mathrm{SmO}}_2\min$ and ${\mathrm{SmO}}_2\max$ for (a) VL, (b) VM, (c) RF, and (d) G. A priori EI is set at $\pm 5\%$ (shaded area). The solid line identifies the mean bias (MB) and dashed lines identify the upper and lower limits of agreement at $\pm 1.96\mathrm{SD}$. For both the MB and the limits of agreement, respectively, dotted lines represent 95% CI.
