a
P for adjusted β-coefficient.
b
Overall model was also adjusted for propensity score, age, gender, race, previous asthma hospitalization, chronic asthma medication, β-agonist receipt, pleural drainage procedures, chest computed tomography or ultrasound, respiratory support, vasoactive infusions, ICU admission, arterial blood gas measurement, blood culture, and empiric antibiotic regimen.
c
Stratified models were adjusted only for propensity score.
