From the random effects IVW analysis, the causal estimates of ADAMTS13 on endometriosis of the uterus remained borderline significant (IVW: OR = 0.45, 95%CI: 0.20-–1.02, P = 0.051), while the causal estimates for endometrioses of the ovary (IVW: OR = 0.48, 95%CI: 0.13–1.79, P = 0.274) and pelvic peritoneum (IVW: OR = 0.32, 95%CI:0.08–1.32, P = 0.116) attenuated towards non-significance (Additional file 1: Table S8). Here, ADAMTS13 is linked to adenomyosis.
