Factors Associated with Hospital Mortality in Our Study Population
| Multivariable Model* | Odds Ratio (95% CI) | P Value |
|---|---|---|
| Age, yr | 1.025 (1.017–1.034) | <0.0001 |
| BMI, kg/m2 | 0.966 (0.946–0.985) | 0.0006 |
| Nonpulmonary (adjusted for missing values) SOFA score | 1.128 (1.085–1.172) | <0.0001 |
| Immune incompetence (reference: no) | 1.989 (1.424–2.777) | <0.0001 |
| Chronic liver disease (reference: no) | 3.486 (1.684–7.217) | 0.0008 |
| ARDS risk factors (reference: no) | 1.823 (1.065–3.122) | 0.0287 |
| pH, per 0.01 unit increase | 0.979 (0.968–0.991) | 0.0004 |
| Crs, per ml/cm H2O increase | 0.988 (0.979–0.996) | 0.0049 |
Definition of abbreviations: ARDS = acute respiratory distress syndrome; BMI = body mass index; CI = confidence interval; Crs = respiratory system compliance, ml/cm H2O; SOFA = Sequential Organ Failure Assessment.

On 1,035 patients; patients with Crs > 150 ml/cm H2O (n = 7; 0.6%) were considered as outliers and were excluded.
