Psoriasis was defined\u00a0\u2265\u00a02 International Classification of Diseases 10<jats:sup>th<\/jats:sup> revision (ICD\u201010) L40 codes. Among them, severe psoriasis was defined as psoriatic medication use, including acitretin, systemic corticosteroid, cyclosporine and methotrexate. Other psoriasis was defined as mild psoriasis. Herpes zoster was defined as\u00a0\u2265\u00a02 ICD\u201010 B02 codes or \u2265\u00a01 B02 code with antiviral medication use. Psoriasis patients (<jats:italic>n<\/jats:italic>\u00a0=\u00a011\u00a0009) and control participants (<jats:italic>n<\/jats:italic>\u00a0=\u00a044\u00a0036) were matched 1:4 by age, sex, income and region of residence. A stratified Cox proportional hazard model was used stratified by age, sex, income and region of residence. Crude and adjusted hazard ratios (HRs) were calculated for the risk of herpes zoster in the total psoriasis group, mild psoriasis group, and severe psoriasis group and compared with those in each matched control group.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>The HR for herpes zoster was higher in the psoriasis group than in control group (adjusted HR\u00a0=\u00a01.22, 95% CI\u00a0=\u00a01.12\u20131.33, <jats:italic>P<\/jats:italic>\u00a0&lt;\u00a00.001).
