It is noteworthy that our result is in agreement with Zhao and colleagues [40], which suggested no evidence for an association between endometriosis and the VEGF -2578C > A, -460 T < C, +405G > C and +936C < T SNPs, when considered together in a larger number (958 cases and 959 controls) of Australian women. This evidence concerns the gene VEGFA and endometriosis.
