This study investigated the association between PSO and peripheral arterial disease (PAOD).</jats:p></jats:sec><jats:sec><jats:title>Methods</jats:title><jats:p>A retrospective cohort study design was carried out between 2000 and 2018. The exposure subject was a newly diagnosed PSO. The diagnosis of PSO was never elaborated as a comparison subject. Balanced heterogeneity of the two groups was used by propensity score matching. The cumulative incidence of PAOD between the two groups was performed using Kaplan-Meier analysis. The Cox proportional hazard model was used to measure the risk of PAOD risk hazard ratio.</jats:p></jats:sec><jats:sec><jats:title>Results</jats:title><jats:p>After matching the 1: 1 propensity score, 15,696 subjects with PSO and the same number of subjects without the diagnosis of PSO were recruited. The PSO subject had a higher risk of PAOD than the non-PSO subject (adjusted HR = 1.25; 95% CI = 1.03-1.50). In the 40-64-year-old subgroup, the subject of PSO exhibited an increased risk of PAOD than the subject without PSO.</jats:p></jats:sec><jats:sec><jats:title>Conclusion</jats:title><jats:p>Psoriasis is associated with an increased risk of peripheral arterial disease and curative care is necessary to reduce the risk of PAOD..</jats:p></jats:sec>journal-article
