However, to the best of our knowledge, no dose\u2010response meta\u2010analysis has been performed to date. This study aims to investigate the association between alcohol consumption and psoriasis. The search was performed on July 27, 2021, using Embase and MEDLINE. The restricted cubic spline analysis was used to perform a dose\u2010response analysis. We identified 3,904 studies, of which 48 studies with 1,702,847 individuals across 24 countries were included. Alcohol consumption was positively associated with psoriasis (odds ratio [OR], 1.47; 95% confidence interval [CI], 1.27\u20101.70). In addition, a significantly increased OR for psoriasis was observed in males (OR, 1.84; 95% CI, 1.13\u20133.01) but not in females (OR, 1.22; 95% CI, 0.97\u20131.54). Based on eight studies, including three cohort and five case\u2010control studies, the analysis revealed that with each additional gram of daily alcohol intake, the OR for psoriasis increased by 4%. We found a positive association between alcohol consumption and psoriasis. The association is more prominent in the group drinking more than 45\u00a0g of alcohol per day (3.2 alcoholic drink equivalent).<\/jats:p>","DOI":"10.1111\/ddg.15380","type":"journal-article","created":{"date-parts":[[2024,4,28]],"date-time":"2024-04-28T23:24:31Z","timestamp":1714346671000},"page":"641-652","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":9,"title":["Dose\u2010response
