Predictors and nomogram of in-hospital mortality in sepsis-induced myocardial injury: a retrospective cohort study

Table 3 The AUROC and IDI of Nomogram, SOFA score and Troponin T in training cohort and validation cohort

Predictive Model		AUROC	p ^a	IDI	P
Training cohort	Nomogram	0.743 (0.716–0.770)
	SOFA score	0.674 (0.641–0.707)	< 0.001	10.31% (8.31%-12.31)	< 0.001
	Troponin T	0.666 (0.629–0.703)	< 0.001	9.93% (7.83%-12.03)	< 0.001
Validation cohort	Nomogram	0.744 (0.691–0.797)
	SOFA score	0.694 (0.663 − 0.625)	< 0.001	7.05% (4.25-9.85%)	< 0.001
	Troponin T	0.642 (0.589–0.695)	< 0.001	8.23% (5.23-11.23%)	< 0.001

AUROC area under the receiver operating characteristic curve, IDI integrated discrimination improvement, SOFA sequential organ failure assessment, IDI integrated discrimination improvement
The P value was drew by comparing the results of Nomogram with SOFA score and Troponin T, respectively
^a The comparisons of AUROC between models were performed by Delong’s test
