AUC in ROC analysis for manual and automated strain values; GLS, GCS 3 slices and GCS all slices, GRS 3 slices and GRS all slices.

Parameter	Manual	Automated	p value
GLS	0.693	0.691	0.801
GCS 3 slices	0.686	0.668	0.425
GCS all slices		0.646	0.055
GRS 3 slices	0.642	0.630	0.537
GRS all slices		0.640	0.827

The AUC was extracted from the ROC graph for manual and automated strain analysis. P was calculated with using the DeLong et al. approach²¹. Automated GCS and GRS all slices were compared to the manual method of obtaining the average of 3 slices. AUC, area under the curve; GCS, global circumferential strain; GLS, global longitudinal strain; GRS, global radial strain. ROC, receiver operating characteristic.
