Table 3. Multivariable Cox regression analysis of SHR for clinical outcomes.

Outcome	Model 1			Model 2			Model 3
	HR (95% CI)	P-value		HR (95% CI)	P-value		HR (95% CI)	P-value
Hazard ratio (HR) with 95% CI was estimated using Cox proportional hazards regression. Model 1: adjusted for age, sex, and body mass index. Model 2: adjusted for variables in Model 1 plus the smoking, DM, hypertension, prior myocardial infarction, and clinical presentation. Model 3: adjusted for variables in Model 2 plus the LVEF, multivessel disease, ≥ 2 stents, statin, LDL-C, stent implantation, and cardiac troponin I. DM: diabetes mellitus; LDL-C: low-density lipoprotein cholesterol; LVEF: left ventricular ejection fraction; MACE: major adverse cardiovascular event; SHR: stress hyperglycemia ratio.
