4) We did not measure Tg Ab in this study and thyroid autoimmunity was evaluated based only on serum TPO Ab measurement; however the presence of TPO Ab in serum is more frequent than Tg Ab [43]; furthermore a large population based study demonstrated a similar prevalence in both antibodies [44] and finally our study assessed only thyroid autoimmunity in relation to age specific AMH levels and autoimmunity in general was not assessed. This evidence concerns the gene AMH and Autoimmunity.
