Models of the association between pre-ICU health categories and hospital- and 3-year mortality. All statistical testing is comparing each group with the Robust category
| Pre-ICU health categories | Number Hospital Deaths/Total at Risk (%) | Hospital mortalitya AOR (95% CI)b |

Notes
Abbreviations: ICU – Intensive Care Unit; AOR – Adjusted Odds Ratio; AHR – Adjusted Hazard Ratio
a
For the outcome of hospital mortality we used logistic regression models and for 3-year mortality Cox proportional hazard models
b
Multivariable models were adjusted for age, sex, race/ethnicity, acute renal failure, severe sepsis and mechanical ventilation (see text for details)
