aColumn data are number of deaths (%). Severe: high risk (> 50%) of death; Moderate: intermediate risk of death; Mild: low risk (< 5%) of death. RTS: Revised Trauma Score; T-RTS: Triage RTS; TRISS: Trauma and Injury Severity Score; MGAP: Mechanism, Glasgow Coma Scale, Age and Arterial Pressure; GAP: Glasgow Coma Scale, Age, and Systolic Blood Pressure.
