Multiple logistic regression models analysing 30-day mortality and the association between index year, sex, and age for all admitted patients and in acute surgically treated, respectively. The 15-year study period was divided into three 5-year time groups where the latter two time groups were compared with the first time group. Patients were divided into five different age groups and the latter four were compared to the first age group. Mean age is presented for each time period and for men and women, respectively. Models are adjusted for index year, sex, and age, respectively as well as for concomitant disorders.
