Association of the triglyceride-glucose index with all-cause and cardiovascular mortality in patients with cardiometabolic syndrome: a national cohort study

Table 3 Threshold effect analysis of TyG index on all-cause and cardiovascular mortality in patients with cardiometabolic syndrome^a

	HR (95% CI)	P value
All-cause mortality
Fitting by the standard Cox proportional risk model	1.16 (1.03, 1.31)	0.017
Fitting by the two-piecewise Cox proportional risk model
Inflection point	9.104
TyG index < 9.104	0.58 (0.38, 0.90)	0.015
TyG index ≥ 9.104	1.35 (1.17, 1.55)	< 0.001
P for Log-likelihood ratio	< 0.001
Cardiovascular mortality
Fitting by the standard Cox proportional risk model	1.39 (1.14, 1.71)	0.001
Fitting by the two-piecewise Cox proportional risk model
Inflection point	8.758
TyG index < 8.758	0.39 (0.12, 1.27)	0.119
TyG index ≥ 8.758	1.54 (1.25, 1.90)	< 0.001
P for Log-likelihood ratio	0.001

HR hazard ratio, CI confidence interval, TyG index triglyceride-glucose index
Cox proportional hazard models were used to estimate HR and 95% CI
^aAdjusted for age, gender, race, education level, family income-poverty ratio, marital status, physical inactivity, BMI, nicotine exposure, and alcohol use
