Non-adjusted model for: None. Adjust I model for: (1) Age (years); and (2) Gender. Adjust II model for: (1) Age (years); (2) Gender; (3) Hamilton Anxiety Scale; (4) Systolic pressure (mmHg); (5) Diastolic pressure (mmHg); (6) Anti-thyroglobulin (IU/L); (7) Thyroid peroxidase antibody (IU/L); (8) Fasting blood glucose (mmol/L); (9) Total cholesterol (mmol/L); (10) High-density lipoprotein cholesterol (mmol/L); (11) Triglycerides (mmol/L); (12) Low-density lipoprotein cholesterol (mmol/L); and (13) Body mass index (kg/m²).
