Model 1 was adjusted for age; model 2 was adjusted for age, sex, ALB, ALT, AST, Scr, BUN, d-dimer, INR, eGFR, and hypertension grades; model 3 was adjusted for all covariables in model 2 plus LDL-C, HDL-C, and LPa. The enalapril group served as the reference group. value for the interaction test: 2-way interaction of TyG (total TyG and tertiles) and hypertension grades (grades 1-2 hypertension vs. grade 3 hypertension) with SUA. tTyG, total triglyceride-glucose index; other abbreviations as in Tables 1 and 2. Statistically significant P-values in bold for a better follow-up of the results.The bold values mean that the differences are significant. And in the 1st -3rd tertiles, the TyG index had a strong significant association with SUA in the grades 1 -2 hypertension group compared to that in the grade 3 hypertension group (P for interaction <0.05).
