Predictors of Pneumothorax/Pneumomediastinum Development on Multiple Logistic Regression Analysis
| Variable | OR | 95% CI | p Value |
|---|---|---|---|
| Time from symptom onset to intubation, d | 1.14 | 1.02 to 1.27 | 0.017 |
| Total bilirubin, day 2, mg/dL | 1.79 | 1.12 to 2.87 | 0.015 |
| Pao2/Fio2 ratio, day 5, mmHg/% | 0.99 | 0.98 to 1.01 | 0.435 |
Only variables with univariate p value <0.1 were included, after exclusion for collinearity/overfitting.
Abbreviations: CI, confidence interval; OR, odds ratio; Pao2/FiO2, partial arterial oxygen tension-to-fraction of inspired oxygen ratio.
