After adjusting for age, sex, education level, race, smoking status, BMI, ALT, AST, triglycerides, total cholesterol, uric acid, eGFR, urine iodine, DM, and hypertension (Model 3), we found that FT4 was positively correlated with albuminuria (OR = 1.12; 95% CI = 1.02–1.23, p = 0.02). Here, GPT is linked to hypertensive disorder.
