Bland-Altman plots showing intra- (top) and interobserver (bottom) CMR-PWV variability. Intraobserver variability for CMR-PWV was low for all 3 observers, 0 ± 0.03 m/s (15 years; left), -0.04 ± 0.33 m/s (4 years; middle), and -0.02 ± 0.30 m/s (<1 year; right), respectively. The interobserver variability was also generally low, for 4 vs. 15 years -0.01 ± 0.32 m/s (left), <1 vs. 15 years 0.01 ± 0.30 m/s (middle), and <1 vs. 4 years 0.02 ± 0.38 m/s (right). Dotted lines indicate mean differences and dashed lines represent 95 % limits of agreement
