Furthermore, stratification analysis by BMI was performed in the studied population, after adjustment for age, BMI, drinking, hypertension, treatment, TG and ALT, the results showed that LDL-C was positively correlated with SUA/SCr in the group with a BMI of 24–28 (β = 0.51, 95%CI 0.22–0.80; P < 0.001) and BMI of 28 or greater (β = 0.30, 95%CI 0.05–0.55; P = 0.019), whereas no association was found in the group with BMI of less than 24 (P = 0.070, Table 3).In addition, we also conducted smooth curve fitting analysis in different BMI groups after adjusting for the above confounding factors. The gene discussed is GPT; the disease is Hypertension.
