CRP and polycystic ovary syndrome: Serum DHA concentrations and the serum-to-cervical mucus DHA ratio differed significantly across PCOS phenotypes and the control group in global comparison (p = 0.023 and p = 0.014, respectively), whereas cervical mucus DHA (p = 0.073) and CRP levels (p = 0.252) did not show significant differences (Table 3).
