Notes

Abbreviations: ICU – Intensive Care Unit; AOR – Adjusted Odds Ratio; AHR – Adjusted Hazard Ratio

For the outcome of hospital mortality we used logistic regression models and for 3-year mortality Cox proportional hazard models

Multivariable models were adjusted for age, sex, race/ethnicity, acute renal failure, severe sepsis and mechanical ventilation (see text for details)
