Bland-Altman plots for lumen volume (a inter-scan, b intra-observer, c inter-observer), normalized wall index (d inter-scan, e intra-observer, f inter-observer), and mean wall thickness (g inter-scan, h intra-observer, i inter-observer). The solid lines represent the mean difference, and the dashed lines indicate the 95% limits of agreement. SD = standard deviation
