Our study clearly demonstrates, using forward LR analysis, that the rs9939609 variant of the FTO gene is significantly associated with the mFG score for hirsutism (OR = 1.1, 95%CI = 1.02–1.23, p < 0.05) and serum testosterone levels (OR = 1.1, 95%CI = 1.02–1.29, p < 0.05) that remained significant after controlling for confounders (Table 3). The gene discussed is FTO; the disease is Hirsutism.
