See Table 1 for the FT3 quartiles definition. Data are odds ratios (ORs, 95% confidential interval).
Model 1 is unadjusted.
Model 2 is adjusted for age, sex, BMI, and smoking and drinking status.
Model 3 is adjusted for age, sex, BMI, smoking and drinking status, SBP and DBP, TC, triglycerides, FPG and OGTT-2 h PG, TPOAb and TgAb, hs-CRP, use of ACEI/ARB drugs, and eGFR.
