The observed frequency of CKD patients with concurrent autoimmune thyroid disease in this study 14/184 (7.6%) for Tg-Abs and 29/184 (15.8%) for TPO-Abs are partially close to 82/1032 (7.9%) for Tg-Abs and TPO-Abs reported in a retrospective study in China [22]. This evidence concerns the gene TPO and autoimmune thyroid disease.
