  1. If only one variable cannot be obtained, then a zero value is given for the missing predictor variable in each equation.
  2. Actual survivals just crossed 50% around the nearest integer value of β (7 or 9)
  3. cAGE: coded value of age, cBP: coded value of systolic blood pressure, cGCS: coded value of the Glasgow Coma Scale score, cRR: coded value of respiratory rate, cISS: coded value of the Injury Severity Score
