Positive correlations were identified between FT3 and FT4 levels, between FT3 andIL-6 levels, between FT3 and IL-18 levels, between FT4 and TSH levels, betweenFT4 and IL-6 levels, between TSH and IL-6 levels, and between TSH andTNF-α levels in the HT group (r = 0.715, r = 0.756, r = 0.710, r = 0.731,r = 0.943, r = 0.760, and r = 0.722, respectively). Here, IL6 is linked to hematocrit.
