  1. aPsychiatric disorder cases = having had a history of hospital admission for at least one psychiatric diagnosis as the primary diagnosis according to ICD-10-criteria: DF20–29: primary psychotic disorders, and DF30–39: affective disorders in the time period from 10 years to 120 days prior to the colorectal cancer operation
  2. bOdds ratio (OR) with 95% confidence interval (CI), adjusted for age, gender, Charlson Comorbidity Index score, cancer stage at the time of operation, educational level, socio-economic position
  3. cCurative or intended palliative aim of the operative treatment among colon and rectal cancer patients combined regardless of acute or not
  4. dOncological treatment = Received at least one oncological treatment (chemotherapy or radiotherapy), by cancer site
