This isn't a new study. I found the explanation interesting. Before I began thyroid treatment my total cholesterol ran 170-176. My cholesterol after thyroid treatment is 160 or a bit lower.

Abstract

Thyroxine and tri‐iodothyronine are essential for normal organ growth, development and function. These hormones regulate the basal metabolic rate of all cells, including hepatocytes, and thereby modulate hepatic function; the liver in turn metabolizes the thyroid hormones and regulates their systemic endocrine effects. Thyroid dysfunction may perturb liver function, liver disease modulates thyroid hormone metabolism, and a variety of systemic diseases affect both organs. We highlight the intricate relations between the thyroid gland and the liver in health and disease.
