Bland-Altman analysis of agreement between Evaluation A and Evaluation B for tricuspid annular plane systolic excursion (TAPSE), fractional area change (FAC, %) and global right ventricular longitudinal strain (RVLSS). The black line represents the mean of the differences between Evaluation A and Evaluation B. The grey dashed lines represent the 95% confidence interval (CI). A: The black line represents the mean of the differences between TAPSE at Evaluation A and Evaluation B. The grey dashed lines represent the 95% CI (0.51071 and -0.57771 respectively). Unstandardized beta coefficient -0.282, P=0.06 (no proportional bias). B: The black line represents the mean of the differences between FAC at Evaluation A and Evaluation B. The grey dashed lines represent the 95% CI (14.7392 and -11.3522 respectively). Unstandardized beta coefficient -0.139, P=0.316 (no proportional bias); C: The black line represents the mean of the differences between global RVLSS at Evaluation A and Evaluation B. The grey dashed lines represent the 95% CI (6.10929 and -4.10929 respectively). Unstandardized beta coefficient -0.110, P=0.348 (no proportional bias)
