  1. COPD, chronic obstructive pulmonary disease; CAP, community-acquired pneumonia; PSI, pneumonia severity index; higher PSI class refers to higher risk for mortality; *expressed as median (Interquartile range, IQR);
  2. Note: there was no statistical difference in baseline characteristic between both groups.
