Multivariate analysis for the predictors of 1-year all-cause death in patients with normal pre-percutaneous coronary intervention baseline cardiac troponin levels

	Crude OR (95% CI)	Adj. OR (95% CI)	P-value
Major procedural myocardial injury	2.66 (1.55–4.56)	2.29 (1.32–3.97)	0.004*
Diabetes	1.75 (1.02–3.00)	1.80 (1.04–3.13)	0.04*
Smoker	1.03 (0.75–1.40)	1.37 (0.97–1.94)	0.074
Age (risk per 5 years increase)	1.44 (1.26–1.66)	1.44 (1.23–1.68)	<0.001*
eGFR <60 mL/min	2.08 (1.22–3.55)	1.17 (0.64–2.12)	0.61
Left main or proximal left anterior descending artery	1.02 (0.68–1.57)	1.04 (0.69–1.62)	0.79
Prior myocardial infarction	1.02 (0.65–1.60)	1.15 (0.73–1.82)	0.55
Prior coronary artery bypass graft surgery	1.36 (0.77–2.89)	1.14 (0.53–2.46)	0.73
Women	0.90 (0.49–1.84)	1.11 (0.57–2.17)	0.75
Hypertension	1.36 (0.77–2.41)	1.14 (0.53–2.46)	0.87

Variables with a univariate associated with 1-year mortality (P < 0.2) were included in the multivariate model: major procedural myocardial injury, age (per 5 years increase), diabetes, active or prior smoking, hypertension, prior MI, prior coronary artery bypass graft surgery, multivessel stenting, number of stent. Number of observations = 9004, AIC value = 576.

^*A significant P < 0.05.
