Table 13 Receiver operating characteristic curve parameters of the predictive model for myocardial injury after non-cardiac surgery in elderly patients with hypertension undergoing gastrointestinal tumor surgery

Variable	AUC	95%CI		aP value	Cut-off	Sensitivity (%)	Specificity (%)
		Lower	Upper
Tumor type	0.658b	0.543	0.760	0.012	Non-colon cancer	87.50	50.00
Anesthesia method	0.679	0.565	0.779	0.006	General anesthesia + remimazolam	75.00	60.71
NT-proBNP at T7	0.680	0.567	0.780	0.007	647.2 pg/mL	54.17	80.36
NT-proBNP at T8	0.704	0.592	0.801	0.001	412.6 pg/mL	58.33	76.79
MINS predictive model	0.765	0.656	0.852	< 0.001		91.67	50.00

^aP < 0.05 vs the reference line (area under the curve = 0.500).

^bP < 0.05 vs the myocardial injury after non-cardiac surgery predictive model.

AUC: Area under the curve; CI: Confidence interval; NT-proBNP: N-terminal pro-brain natriuretic peptide; MINS: Myocardial injury after non-cardiac surgery.
