Stratified analyses of the associations between the TyG index and all-cause (a) and cardiovascular mortality (b) among respondents with cardiometabolic syndrome. Hazard ratios were estimated using a two-piecewise Cox proportional risk model on both sides of the inflection point (all-cause mortality: 9.104; cardiovascular mortality: 8.758) and adjusted for confounders. Alcohol use was defined as more than 10 drinks per month. HR hazard ratio, CI confidence interval, TyG index triglyceride-glucose index, NH non-Hispanic
