In Table 2 we can see that when compared with the other three groups (endometriosis without an LBW history, non-endometriosis with an LBW history, and non-endometriosis without an LBW history), endometriosis patients with an LBW history had the highest median of PR-B methylation, DNMT1 expression, PR-B receptor expression, and VEGF expression (p < 0.001). Here, VEGFA is linked to endometriosis.
