Socioeconomic position was determined by highest attained educational level, income, urbanicity and cohabitation status, obtained from administrative registries. Co-variables included age, sex, year of surgery, Charlson Co-morbidity Index score, smoking status, alcohol consumption, BMI, stage and tumour localization. Logistic regression analysis was performed to determine the likelihood of acute colorectal cancer surgery, and Kaplan\u2013Meier and Cox proportional hazards regression methods were used for analysis of 1-year overall survival.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>In total, 35\u2009661 patients were included; 5310 (14\u00b79 per cent) had acute surgery.
