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.
