Bland–Altman plots of left ventricular ejection fraction (LVEF) (a) and right ventricular ejection fraction (RVEF) (b) measures between automated and manual measurements. The middle line denotes the mean difference (bias) and the two dashed lines denote ± 1.96 standard deviations from the mean. The plot a shows a mean difference of 0.4% with 95% limits of agreement being from -2.7% to 3.5% for LVEF. The plot b shows a mean difference of 1.9% with 95% limits of agreement being from -8% to 11.8% for RVEF
