CCL2 and inflammatory bowel disease: Results were largely consistent with those from the Immunochip analysis for the single shared SNP (rs2036297), but overall estimates for IBD and UC were null, whereas the association between MCP‐1 and CD (OR 1.2; 95% CI: 1.05‐1.38; P = 0.01) was in the opposite direction to that observed using the Immunochip data set (Figures 3 and 4, Supporting Information Table S18).
