  1. ICU intensive care unit, HR hazard ratio, CI confidence interval
  2. Model was adjusted for age, gender, primary diagnosis (congenital anomalies, injury, respiratory disease, neoplasms, neurologic disease, circulatory disease, NEC (not elsewhere classified), gastrointestinal disease and infectious disease), and treatment requirements (vasopressor, extracorporeal membrane oxygenation, and mechanical ventilation)
  3. Mechanical ventilation was adjusted only in the overall analysis
  4. P-for interaction 0.002, 0.48, and 0.40 with re-admission, re-admission to ICU, and emergency room visit
