Summary of comparisons and raters. A The intraclass correlation coefficient (ICC) was calculated for the ML model estimated left ventricular ejection fraction (LVEF) of single videos as compared with the aforementioned five reference standards. The reference standards were established by a level III echocardiographer by 4 different methods and the derived LVEF using formal echocardiogram reports. B The ML model LVEF was calculated at the participant level by averaging the single video estimates for LVEF. The participant ML model LVEF was used for ICC calculation by comparing with 5 reference standards; 2 methods which required averaging of expert LVEF estimates across single videos
