Moreover, SHBG was the biochemical marker that best correlated with the following metabolic parameters: BMI (r = −0.531, p = 0.001), waist (r = −0.502, p = 0.001), HOMA-index (r = −0.468, p = 0.001), HbA1c (r = −0.300, p = 0.046), and hirsutism severity (r = −0.404, p = 0.001). The gene discussed is SHBG; the disease is Hirsutism.
