Threshold effect analysis of TyG index on all-cause mortality, weighted.

Model	HR (95% CI)	P-value
Model I (Linear association)	1.17 (1.01–1.35)	.026
Model II (Threshold effect)
Inflection point (K)	9.06	–
95% CI for inflection point	8.92–9.26	–
TyG index < 9.06	0.88 (0.69–1.11)	.304
TyG index > 9.06	1.44 (1.05–1.96)	.020
P for Log-likelihood ratio	–	.001

Cox proportional hazards models were used to estimate HR and 95% CI. Adjusted for age, ethnicity, marital status, poverty income ratio, education level, smoking status, alcohol use, hypertension, and body mass index.

CI = confidence interval, HR = hazard ratio, TyG = triglyceride-glucose.
