Conversely, VEGFA expression (Figure 1H) was significantly lower in ovarian endometriosis (7.03, 6.89–7.24) relative to all other tissues, including control (7.40, 7.17–7.71; p = 0.0052), patient endometrium (7.40, 7.24–7.66; p = 0.0007), patient peritoneum (7.44, 7.28–7.66; p = 0.0023), peritoneal endometriosis (7.40, 7.16–7.68; p = 0.0040), and deep infiltrating endometriosis (7.48, 7.17–8.02; p < 0.0001). Here, VEGFA is linked to ovarian endometriosis.
