Nested case-control study on risk factors for opportunistic infections in patients with inflammatory bowel disease

Figure 1 Risk factors for opportunistic infection in inflammatory bowel disease patients (multivariate analysis). 5-ASA: 5-aminosalicylic acid; IS: Immunosuppressant (steroids, thiopurine, thalidomide, tacrolimus, or methotrexate); FC: Fecal calprotectin; CRP: C-reaction protein; ESR: Erythrocyte sedimentation rate; ULN: Upper limit of normal; CI: Confidence interval. P-values and 95% confidence intervals (CIs) for mild, moderate, and severe disease were compared with remission. P-values and 95%CIs for any immunosuppressant (IS), any two IS, infliximab, 5-aminosalicylic acid (5-ASA) + any IS, and infliximab + any IS were compared with 5-ASA.
