Table 4 ROC curve analysis of IBI for in-hospital death in elderly patients with NSTEMI.

	AUC	95% CI	P	Cut-off	Sensitivity	Specificity
IBI	0.760	0.689~0.832	<.001	36.85	0.744	0.717
NLR	0.710	0.639~0.782	<.001	9.12	0.535	0.789
CRP	0.676	0.600~0.753	<.001	2.41	0.860	0.453
CI – confidence interval; AUC – area under curve; IBI – inflammatory burden index; CRP – C-reactive protein; NSTEMI – non-ST-segment elevation myocardial infarction.
