| Outcome | Adjusted OR or standard estimate | 95% CI | P value |
| Mortality (OR) | 0.75 | 0.57 to 0.97 | 0.026 |
| Mechanical ventilation (OR) | 1.48 | 1.01 to 2.16 | 0.045 |
| Hospital LOS (SE) | 0.02 | −0.03 to 0.064 | 0.40 |
| ICU LOS (SE) | −0.03 | −0.08 to 0.01 | 0.15 |
ICU, intensive care unit; LOS, length of stay; NE, norepinephrine.
