Table 3 Se levels expressed in percentage of threshold levels in relation to deiodinases (IDI), plasma glutathione peroxidase (GPx), and selenoprotein P (SePP) [41,42]

From: The role of selenium, vitamin C, and zinc in benign thyroid diseases and of selenium in malignant thyroid diseases: Low selenium levels are found in subacute and silent thyroiditis and in papillary and follicular carcinoma
