From: Acute and long-term survival in chronically critically ill surgical patients: a retrospective observational study

Prognosis HR)/OR (95% CI) P value
Survival time until day 150 after inclusion HR 1.206 (0.871–1.670) 0.260
Survival time until year 3 after inclusion
in patients surviving > 150 days
HR 1.278 (0.653–2.500) 0.474
ICU mortality OR 1.169 (0.551–2.481) 0.684
Two-year mortality rate in ICU survivors OR 1.479 (0.773–2.829) 0.237
