Table 4 Evaluation of the accuracy and reclassification of LV entropy

From: Late gadolinium enhancement entropy as a new measure of myocardial tissue heterogeneity for prediction of adverse cardiac events in patients with hypertrophic cardiomyopathy

	Primary end point
	C-index (95% CI)	NRI (95% CI)	IDI (95% CI)
Model 1 (risk model + LGE)	0.769 (0.693, 0.844)	Baseline	Baseline
Model 2 (risk model + LGE + entropy)	0.872 (0.821, 0.924)	0.332 (0.190, 0.642)	0.138 (0.020, 0.288)

	Secondary end point
	C-index (95% CI)	NRI (95% CI)	IDI (95% CI)
