Relationship between TyG index and cardiovascular events in CTO patients

TyG Tertiles	HR (95% CI)
	Unadjusted	Model 1a	Model 2a	Model 3a
T1	1 (reference)#	1 (reference)#	1 (reference)#	1 (reference)#
T2	1.29 (0.67–2.47)	1.29 (0.67–2.47)	1.32 (0.69–2.52)	1.24 (0.65–2.38)
T3	2.44 (1.35–4.39)	2.44 (1.35–4.39)	2.46 (1.37–4.44)	2.09 (1.14–3.86)

^aThe log-rank test and backward stepwise selection methods in a Cox proportional hazards regression model were performed; Model 1: adjusted for age, sex, BMI; Model 2: Model 1 + current smoker, hypertension, diabetes mellitus, dyslipidemia, previous PCI, previous CABG; Model 3: Model 2 + acute myocardial infarction, FBG, TC, LDL-C, successful CTO treatment, using of statin, ezetimibe, or antidiabetic medication. TyG index tertiles: T1: ≤ 8.50, T2: > 8.50, ≤ 8.95, T3: > 8.95
