We found that ORs of FSH for NAFLD in people age between 60 and 70 years and over 70 years old were 0.983 and 0.973 after adjusting for all confounding factors, respectively (95%CI, 0.967–0.999, P = 0.033 and 0.958–0.989, P = 0.001, respectively) (shown in Table 4). The gene discussed is BRD2; the disease is metabolic dysfunction-associated steatotic liver disease.
