  • a HR > 1 indicates a shorter hospital length of stay (ie, a greater probability of earlier discharge).

  • b Denotes P for adjusted HR.

  • c 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.

  • d Stratified models were adjusted only for propensity score.
