Meanwhile, in obese PCOS patients, serum ANGPTL2 levels were markedly positively correlated with FINS and serum T (all P < 0.05), and negatively correlated with PRL (P < 0.05), but not with other indexes; in nonobese PCOS patients, ANGPTL2 was positively associated with the Ferriman–Gallwey score and FINS (all P < 0.05), inversely correlated with PRL (all P < 0.05), but not with other parameters (Table 4). Here, ANGPTL2 is linked to polycystic ovary syndrome.
