TABLE 5.

Receiver operator curve (ROC) analysis of primary and secondary outcome based on RCRI score and substituted HH-RCRI score.

	AUC	p-value	Sensitivity	Specificity
30-day mortality		<0.001
RCRI score	0.659		0.534	0.761
Substituted HH – RCRI Score	0.691		0.569	0.727
90-day mortality		<0.001
RCRI score	0.669		0.553	0.769
Substituted HH – RCRI Score	0.704		0.591	0.735
Postoperative AMI		<0.001
RCRI score	0.685		0.525	0.787
Substituted HH – RCRI Score	0.713		0.564	0.753
Postoperative AKI		<0.001
RCRI score	0.569		0.376	0.758
Substituted HH – RCRI Score	0.622		0.455	0.728

The sensitivity and specificity are based on a cut-off of 2 (intermediate and high risk). AUC, area under curve; RCRI, lee’s revised cardiac risk index; HH ratio, hemoglobin/HbA1C ratio; Postop, postoperative; AMI, acute myocardial injury; AKI, acute kidney injury. p-value, Delong’s test.
