Cancer site (ICD-10 code), full details Additional File Tables C1 and C4. Adjusted hazard ratio (95% CI). αCharlson index cancer is a weighted factor; hence, zero is not possible in the cancer model. aHazard of death in the first 28 days of admission. bHazard of death within 29 to 365 days of admission, which excludes patients who died before 28 days. Definition: home—usual place of residence in the community including personal dwelling and care home (with or without nursing)
