Relationship between serum free T4 (FT4) levels and metabolic syndrome (MS) and its components in healthy euthyroid subjects

Abstract

These results suggest that the interaction between serum FT4 and MS components could be different according to age as well as gender in euthyroid subjects. Although thyroid hormone significantly affected each component of MS, there was no association between serum FT4 level and presence of MS after adjustment for age in healthy euthyroid subjects.
