  • Model 1 adjusted for age and body mass index (BMI). Model 2 adjusted for age, BMI, smoking and number of comorbidities. Model 3 adjusted for age, hypertension, coronary artery disease and presence of lung disease.

  • *All patients who required intensive care required mechanical ventilation.

  • †Model 2 and model 3 were not performed for mortality outcome due to low event rate.
