Compared with the HT group, the levels of TgAb (P<0.0001), TPOAb (P<0.0001), and IL-17 (P<0.01) in the HT+T group were significantly decreased, while the levels of TgAb (P<0.001), TPOAb (P<0.0001), and IL-17 (P<0.01) in the HT+I group were significantly increased. This evidence concerns the gene IL17A and hematocrit.
