TABLE 3.
MULTIVARIATE REGRESSION MODEL OF FACTORS ASSOCIATED WITH THE DEVELOPMENT OF ACUTE LUNG INJURY: BACKWARD SELECTION
| Predictor | Odds Ratio for Developing ALI (95% CI) | P Value |
|---|---|---|
| Moderate to heavy passive smoke exposure (cotinine, 0.19–3.08 ng/ml) | 2.88 (1.05–7.94) | 0.04 |
| Active smoking (cotinine > 3.08 ng/ml) | 2.83 (1.25–6.39) | 0.01 |
| Injury Severity Score, per one-point increase | 1.04 (1.02, 1.07) | 0.001 |
Definition of abbreviations: ALI = acute lung injury; CI = confidence interval.
Eliminated from the model (in order): Source of medical insurance; composite variable capturing any history of alcohol abuse, or alcohol withdrawal, or alcoholic cirrhosis, or high score on AUDIT, or high blood alcohol level; age; race; sex.
