Circulating Visfatin in Hypothyroidism Is Associated with Free Thyroid Hormones and Antithyroperoxidase Antibodies

Figure 1

Comparison of visfatin serum concentration in hypothyroid patients with chronic autoimmune thyroiditis (AIT), in hypothyroid patients after total thyroidectomy (TT), and in healthy controls (controls). Central box represents the values from the lower to upper quartile (25th to 75th percentile). The middle line represents the median. The thin vertical lines extending up or down from the boxes to horizontal lines (so-called whiskers) extend to a multiple of 1.5 × the distance of the upper and lower quartile, respectively.
