  • RibScore and PaCO2 are continuous variables.

  • Other variables entered in the model: ISS, chronic obstructive pulmonary disease, head injury, face injury, pulmonary contusions, clavicular fracture, spine injury, abdominal injury, pelvic injury and pneumothorax and all the individual components of the RibScore.

  • ISS, Injury Severity Score; PaCO2, partial pressure of carbondioxide.
