FGF5 and polycystic ovary syndrome: Correlation analysis of the unstratified groups showed that BMI was associated positively with the altered VEGF-sR3, FGF5, VEGF-sR2, and VEGF-C (r = 0.23, p = 0.0109; r = 0.19, p = 0.03; r = 0.2, p = 0.02; r = 0.19, p = 0.03, respectively) only in the PCOS subjects as shown in Figure 5, but there was no correlation with BMI and the growth factor-related proteins that differed between PCOS and controls.
