[Effects of levothyroxine replacement on lipid profile in patients with mild subclinical hypothyroidism].

Background And Objective: To evaluate the effects of levothyroxine (L-T4) replacement on lipoprotein profile in patients with mild subclinical hypothyroidism, defined as a serum TSH level between 5 to 10 mU/l with a normal serum free thyroxine level.
