Intra-observer and inter-observer repeatability. Bland-Altmann plots with actual difference (left side) and percentage difference (right side), mean error (blue line) and 95% limits of agreement (red lines) for Intra-observer values (a), and inter-observer (b). Y-axis limits in the actual difference plots are set to the mean AMA value. AMA, aortic microcalcification activity; CR, coefficient of reproducibility; ICC, intraclass correlation coefficient; LOA, limits of agreement; TBR, tissue-to-background ratio
