A and B: A (a-d). Inter- and intra-observer reproducibility of the manual and automated analyses. Bland-Altman plots showing inter-observer and intra-observer reproducibility of RV displacements by the manual (a and c) and automated (b and d) techniques. The automated analysis showed closer 95% limits of agreement than manual analysis. B. Inter-study reproducibility of RV displacement Bland-Altman plots showing inter-study reproducibility with closer 95% limits of agreement when analysed with the automated technique compared with the manual technique.
