Inflammatory bowel disease, RA, and MS are Th1-related autoimmune disorders, meta-analyzing across these three traits yielded to a reduced effect with marginal significance [OR meta (95%CI) = 0.79 (0.63–1.01), P = 0.06 using all IVs; OR meta (95%CI) = 0.70 (0.51–0.95), P = 0.02 using IVs excluding confounders].
