NGFR expression (Figure 1J) was significantly upregulated in patient peritoneum (7.48, 7.10–7.89), peritoneal endometriosis (7.24, 6.88–7.66), and deep infiltrating endometriosis (6.99, 6.65–7.48) compared to control (6.47, 6.32–7.15) and patient endometrium (6.50, 6.36–6.59) (all p < 0.0001). Here, NGFR is linked to endometriosis.
