Values in brackets are Q1: 25th percentile and Q3: 75th percentile, SD, standard deviation; Min., minimum value; Max., maximum value. ‡Plasma Se concentration is the standard reference for Se status determination, SELENOP, Selenoprotein P; GPX3, glutathione peroxidase 3; IDI, iodothyronine deiodinase.
