SERPINE1 and polycystic ovary syndrome: mRNA expression of PAI-1 was 1.24 fold which was not significantly higher than the drug-naive PCOS group (Fig. 1, Table 4).PAI-1 expression in the OCP group in terms of CT values positively correlated with post-glucose load 2 h blood glucose (p = 0.008) and triglyceride levels (p = 0.001) (Fig. 2, Table 8).
