Model 1 adjusted for age, sex, ethnicity, Townsend Deprivation Index. Model 2 further adjusted for smoking status, alcohol consumption, history of hypertension and high_cholesterol, SBP, DBP, history of stroke, and diabetes status. TyG, triglyceride-glucose index; BMI, body mass index; WC, waist circumference; WHTR, Waist-to-Height Ratio. HR, hazard ratios; CI, confidence intervals.
