  1. The variables, resident of long-term care facilities and pneumonia severity index score, were not included due to collinearity
  2. RSV respiratory syncytial virus, COPD chronic obstructive pulmonary disease, HR hazard ratio, CI confidence interval. Hazard ratios were calculated using a Cox Proportional hazards regression model
