  1. Se: Selenium; TV:Thyroid volume.
  2. Goiter: thyroid volume ≥ 14.4 mL in female, ≥18.7 L in male; TPOAb (+): TPOAb positive; TgAb (+): TgAb positive; antibody (+): TPOAb and/or TgAb positive.
  3. *Mean ± standard deviation.
  4. **Median (interquartile range).
  5. *** t test or log-transformed t test (selenium and thyroid volume).
  6. Chi-square test.
