Absolute rates of community\u2010acquired pneumonia were calculated for patients with coeliac disease compared to controls stratified by vaccination status and time of diagnosis using Cox regression in terms of adjusted hazard ratios (<jats:styled-content style=\"fixed-case\">HR<\/jats:styled-content>).<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Among 9803 patients with coeliac disease and 101 755 controls, respectively, there were 179 and 1864 first community\u2010acquired pneumonia events.
