  1. ICU: Intensive Care Unit, SpO2 : saturation of peripheral oxygen, RR: respiratory rate, BP: systolic blood pressure, HR: heart rate, GCS: Glasgow Coma Score
  2. Reference: SpO2 = 95-100; RR = 8-25; BP > 90; HR 50-110; GCS = 15
  3. Age is expressed as continuous covariate. The OR at e.g. 1.02 represents the increased risk of ICU admission being 1 year older
