However, there was no significant difference in the risk of RSV infection between patients on thiopurines or methotrexate (aOR, 1.72; 95% CI, 0.787–3.763) and anti-TNF alone (aOR, 1.4; 95% CI, 0.626–3.179) when compared with the IBD non-SARS-CoV-2 control cohort (Table 3). Here, TNF is linked to inflammatory bowel disease.
