Serum urate is associated with an increased risk of inflammatory bowel disease: A bidirectional Mendelian randomization study

Figure 4 Association of inflammatory bowel disease and urate levels in Mendelian randomization analyses (inverse-variance weighted estimate). Estimated odds ratio (OR) represent the effect of per log-OR increase in inflammatory bowel disease on urate levels, using inverse-variance weighted analysis with a fixed-effects model. IBD: Inflammatory bowel disease; UC: Ulcerative colitis; CD: Crohn’s disease; CI: Confidence interval; SNP: Single-nucleotide polymorphisms; UA: Ursolic acid; IVW: Inverse-variance weighted.
