Comparison of 30-day prognostic models with or without adverse events and medications

	30-day model 0	30-day model 1
C index	0.822 (0.796–0.848)	0.855 (0.830–0.879)
NRI (95% CI)	0.445 (0.339–0.523)
P value	<0.0001
IDI (95% CI)	0.040 (0.025–0.074)
P value	<0.0001
Likelihood ratio test (p value)	<0.0001
BIC	3434.091	3350.882

30-day model 0: age, prior stroke, heart rate, Killip class, LVEF and in-hospital PCI. 30-day model 1: age, prior stroke, heart rate, Killip class, LVEF, in-hospital PCI, in-hospital recurrent myocardial ischaemia, in-hospital recurrent myocardial infarction, in-hospital heart failure, antiplatelet therapy and statins at discharge.

BIC, Bayesian information criterion; IDI, integrated discrimination improvement index; LVEF, left ventricular ejection fraction; NRI, net reclassification index; PCI, percutaneous coronary intervention.
