Restricted cubic spline curve for CMM by TyG index after covariate adjustment. Heavy central line represents the estimated adjusted hazard ratio, with shaded ribbons denoting 95% confidence interval. The vertical dotted line indicates the threshold value of TyG index at 8.59. The horizontal dotted line represents the hazard ratio of 1.0. The model is adjusted for age, sex, SBP, DBP, BMI, alcohol consumption and smoking status, marital status, education, rural residence, heart rate, BUN, serum creatinine, UA, hemoglobin, TC, LDL, stroke, heart disease, and DM
