MIF and inflammatory bowel disease: Figure 3 displays the scatter plots and funnel plots depicting the Mendelian randomization analyses for IL13 and MIF in IBD. The results from sensitivity analysis indicated that the MR-Egger regression analysis indicated no presence of horizontal pleiotropy, while the Cochran Q test demonstrated the absence of heterogeneity among IVs (Supplementary Table S1). Details of the SNPs are also presented in Supplementary Table S1. While the forest plots and leave-one-out sensitivity analyses of all suggestively significant regulators are presented in Supplementary Figure S1.
