Figure 4

Echocardiographic estimation of left ventricular ejection fraction. Correlation analysis comparing the various echocardiographic estimations of LVEF with expert manual biplane Simpson (left panels) and corresponding Bland-Altman plots of the difference between them (right panels) a) the manual Simpson method by the novices, b) the corrected AutoEF method by the expert readers, c) the corrected AutoEF method by the novices and d) the uncorrected AutoEF method. Finally, e) displays the correlation between corrected AutoEF performed by either experts (horizontal line) or novices (vertical line). BS = manual Simpson, LVEF = left ventricular ejection fraction
