Table 5 Cumulative incidence of all-cause preoperative mortality, unplanned emergency surgery, and planned surgery in relation to urgency group, for patients registered for bypass surgery in 1992–2005, as measured by odds ratios derived from regression models for pseudovalues of cumulative incidence functions*

From: The occurrence of adverse events in relation to time after registration for coronary artery bypass surgery: a population-based observational study

  1. Abbreviations: CI = confidence interval, OR = odds ratio.
  2. *Did not include 218 patients for whom urgency was not provided: 5 died, 5 had unplanned emergency surgery, 163 underwent planned surgery, 45 removed for other reasons.
  3. †At 52 weeks.
  4. ‡Odds ratio of death adjusted for sex, age decade, comorbidities at registration, calendar period of registration and time between catheterization and registration.
  5. §Odds ratio of admission adjusted for sex, age group, coronary anatomy, comorbidities at registration, calendar period of registration, institution at registration, institution at catheterization, mode of admission at catheterization, urgency at admission for catheterization, and time between catheterization and registration.
