TNF and inflammatory bowel disease: After 1:1 propensity score matching (direct matching by IBD subtype, sex, age at diagnosis, calendar year of diagnosis, and level of education, with propensity scores adjusted for comorbidities and co‐medications), we compared statin users with nonusers applying Cox proportional hazards modeling to estimate the risk of IBD‐related surgery, hospitalizations, and disease flares (any of systemic corticosteroid prescription, start of immunomodulator, or start/switch to anti‐tumor necrosis factor treatment).
