IBD patients who had a dose escalation of their TNFα inhibitor (OR 8.22, 95% CI 3.76–17.93), initiated or intensified immunomodulator treatment (OR 2.13, 95% CI 1.04–4.34), initiated high‐dose corticosteroid treatment (OR 6.91, 95% CI 2.81–17.01) or had a serum concentration measurement (OR 5.44, 95% CI 2.74–10.79) were more likely to switch as well (Table 3). Here, TNF is linked to inflammatory bowel disease.
