Fig. 6.
Bland-Altman plots of agreement of VT and BPND estimates of different models. Bland-Altman plots for analysis of agreement in VT and BPND values between different models. On the top, Bland-Altman plots for agreement between VT estimates from SA and 2TCM (a) and from 1TCM and 2TCM (b). On the bottom, a Bland-Altman plot for agreement between BPND estimates from five different methods in comparison with DVR–1 from the 2TCM. The dashed lines represent zero difference and the y-axis is expressed in %difference. More information on the %difference and 95% limits of agreement for each method can be found in Table 4
