The results (Table 4 and Figure 5) showed that the level of ANGPTL4 expression in ovarian GCs could statistically significantly predict the risk of PCOS patients independent of other clinicopathologic variables after adjusting for AMH, LH/FSH, and T (OR: 3.345; 95% CI: 1.951–5.734). The gene discussed is PLOD1; the disease is polycystic ovary syndrome.
