IL6 and type 2 diabetes mellitus: The strengths of our study are that we thoroughly examined a population of Chinese patients with euthyroid T2D; we characterized multiple thyroid parameters, including TSH, FT3, FT4, TSHI, TF4RI, FT3/FT4 ratio, TFQIFT3, and TFQIFT4; we measured two indices of chronic inflammation (IL6 and IL8); and we performed a binary logistic regression analysis with adjustment for multiple confounding factors.
