ROC curve analyses of different levels of TyG index

	AUC	95% CI	P	Sensitivity	Specificity	Youden’s index
≥ 7.91	0.651	0.599–0.703	< 0.001	0.573	0.645	9.013
≥ 8.78	0.637	0.572–0.701	< 0.001	0.332	0.917	9.548
≥ 9.22	0.702	0.613–0.791	< 0.001	0.590	0.784	9.548

The rule-in threshold of three ROC was respectively minimum value of TyG (7.91) and the tri-sectional quantiles of TyG (8.78, 9.22)
