Fig. 3: Intra- and inter-observer variabilities.

Intra- (A) and inter-observer (B) variabilities assessment. The three dashed lines show biases (means of differences) and LOA. Bias is expressed as the mean of the difference (95% CI). LOA is shown as bias ± 2 SD. LOA limits of agreement, RVEDV right ventricular end-diastolic volume, LVEDV left ventricular end-diastolic volume, SD standard deviation, CI confidence interval.
