Thyroid hormone levels before and after surgery and correlation with DIO2 gene polymorphisms. Presurgical and postsurgical thyroid hormone parameters (a). Presurgical and postsurgical FT3 levels in the “reduced FT3” group (b, panel A) and in the “unchanged FT3” (b, panel B) group. Presurgical and postsurgical FT3 levels in relation to the DIO2 genotype (c). Differences between presurgical and postsurgical serum FT3 levels in the three genotype groups (d). SD, standard deviation; WT, wild-type.
