Comorbidities and systemic steroids drive pneumonia risk in inflammatory bowel disease: Propensity score-matched cohort study

Figure 1 Flowchart of study population selection and propensity score matching process. IBD: Inflammatory bowel disease; PS: Propensity score.

Figure 2 Love plots across all four models. A: Baseline model; B: Model 1; C: Model 2; D: Model 3. AIDS: Acquired immunodeficiency syndrome; TNF: Tumor necrosis factor.

Figure 3 Propensity score distributions for inflammatory bowel disease and non-inflammatory bowel disease groups before and after matching across all models. A: Baseline model; B: Model 1; C: Model 2; D: Model 3. IBD: Inflammatory bowel disease; PS: Propensity score.

A: Cumulative proportion of pneumonia events over follow-up time; B: Number at risk for each group. IBD: Inflammatory bowel disease.
