Values in table represent median percentage [interquartile range] or frequency (proportion). Control: patients presenting with an injury without respiratory symptoms. URI (upper respiratory infection): cough, congestion, or rhinorrhea alone. LRI (lower respiratory infection): hypoxemia ≤92% at triage or wheezing with increased work of breathing.
ICP intermediate care placement, ICU intensive care unit, N/A not available
aKruskal–Wallis equality of populations rank test with p < 0.05.
