Note:

TyG-index (standardization) means that the mean of the TyG index is changed to 0 and the variance is changed to 1. Crude model adjusted for none. Model 1 adjusted for sex, age, BMI, diabetes, family history of hypertension, diuretics, ACEI/ARB. Model 2 adjusted for Model 1 and laboratory indicators (HDL-C, uric acid, creatinine, TC).
