SHBG and polycystic ovary syndrome: Notably, we found weak but strongly significant correlations between mFG and FT (rho(278) = 0.23, p <  0.001), DHEAS (rho(282) = 0.13, p = 0.031), SHBG (rho(275) = −0.30, p < 0.001), FAI (rho(268) = 0.23, p <  0.001), FSH (rho(274) = −0.19, p = 0.001), and BMI (rho(280) = 0.30, p <  0.001) in the PCOS group.
