A positive association between the PB MAIT cells and CA125 from patients with endometriosis was discovered (r = 0.39 and P < 0.05, Fig. 5a), whilst DN MAIT cells were found to be positively related to CD8 MAIT cells in PF from endometriosis (r = 0.62 and P < 0.01, Fig. 5b). This evidence concerns the gene CD8A and endometriosis.
