ROC analysis for differential strain as shown in Fig. 3

Type and layer of strain	AUC	Sens (%) at spec = 80 %	Diff strain cut-off value
Radial subendocardial strain SA	0.51	18	N/A
Radial epicardial strain SA	0.66	36	N/A
Radial transmural strain SA	0.61	30	N/A
Radial transmural radial strain LA	0.63	28	N/A
Circumferential subendocardial strain	0.95	94	−2
Circumferential epicardial strain	0.94	91	−2
Circumferential transmural strain	0.95	94	−2
Longitudinal transmural strain	0.83	72	−2

Differential strain (for definition see text) for segments with transmurality in excess of 50 % (80 segments) is compared with differential strain in 356 control segments, regardless of location. AUC is presented together with sensitivity at 80 % specificity and the corresponding cut-off value for differential strain, when available
