However, the link between PsA infection and CV events in BE is unknown. Thus, we investigated whether there is an association between PsA airway infection and the risk of CV events post-exacerbation.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>This was a US retrospective cohort study using the TriNetX platform between 2008 and 2019. Adult patients with (wPsA) or without (w\/oPsA) PsA airway infection were included. Date of first exacerbation corresponded to the index date, and patients were followed for up to 5\u2005years post index. Risk ratios (RR) for hospitalisation, subsequent exacerbation, mortality and incidence of pre-specified CV events were estimated. Propensity score matching (PSM) was used to balance baseline characteristics.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>After PSM, patients wPsA infection were at a greater risk of hospitalisation (RR: 1.40; 95% CI: 1.19\u20131.64), subsequent exacerbation (RR: 1.70; 95% CI: 1.53\u20131.90) and mortality (RR: 1.37; 95% CI: 1.20\u20131.56) than patients w\/oPsA.
