Pairwise comparison of ROC curves of HEART, HET, TIMI, GRACE, EDACS-ADP

Stratification tool Comparison	Differences between areas	P-value
HEART ~ HET	0.0194	0.2326
HEART ~ TIMI	0.0568	0.0001
HEART ~ EDACS-ADP	0.122	< 0.0001
HEART ~ GRACE	0.110	< 0.0001
HET ~ TIMI	0.0374	0.0707
HET ~ EDACS-ADP	0.103	0.0007
TIMI ~ EDACS-ADP	0.0654	0.0215
TIMI ~ GRACE	0.0534	0.0242

^* The Delong test was used for pairwise comparison of the tools, however, due to the missing data the results for the GRACE score should be interpreted with caution
