Figure 4

Regression and Bland-Altman analyses of right ventricular stroke volume and ejection fraction with manual correction. To the left is shown the linear regression analysis of right ventricular stroke volume (SV) and ejection fraction (EF) using 3-dimensional echocardiography (3DE) images against cardiac magnetic resonance (CMR), when manually correcting the semi-automatic delineation. Dashed line shows the linear regression line and full line the identity line. To the right is shown the Bland-Altman plot for SV and EF. The full lines show bias and the dashed lines are the limits of agreement (LOA) of ± 1.96 standard deviation (SD).
