  1. 1 TSH = thyroid stimulating hormone (normal range 0.3-4.0 mIU/L).
  2. 2 TPO = thyroid peroxidase (cut-off titre 100).
  3. 3 A positive test for thyroid stimulating antibodies (TSI) was taken as a % B/BO >19%, a positive test for TSH-R binding inhibitory immunoglobulin (TBII) was taken as >1.5 IU/Litre.
  4. 4 Number of patients treated with thyroxine (L-T4), 131I or antithyroid drugs (ATD).
  5. 5 GD = Graves’ disease.
