Bland–Altman plots comparing inter-CAD user variability in measurement of the pulmonary trunk (left) and pulmonary main (right). In each plot, the differences (in mm) are plotted against average measurements (in mm) of the corresponding two methods. Dashed lines represent the mean difference of the two methods, and the 95% limits of agreement (±1.96 SD). The solid line is the zero baseline.
