Correlation and Bland-Altman plots for the PWV computation between the automatic method and manual computations, foot-to-foot method (a), half-max method (b), and cross-correlation (c).For the correlation plots (left) solid line indicates the line of best fit and the dashed line shows the diagonal reference line. For the Bland-Altman plot (right) the solid line shows the bias and the dashed lines show the 95% confidence interval
