In the dominant model, the comparison of VEGF (CA+AA) versus the CC genotype revealed an increased susceptibility to PCOS, with an odds ratio of 1.80 (95% CI = 1.0888 to 2.9971), RR = 1.33 (95% CI = 1.0451 to 1.7079), and p < 0.022. This evidence concerns the gene VEGFA and polycystic ovary syndrome.
