  1. aMissing prehospital data are gender (n = 7), transporter (n = 1,009), SBP (n = 7,364), DBP (n = 10,131), HR (n = 5,797), RR (n = 7,386). Missing data at the ED are alcohol drunk (n = 9,649) and BT (n = 3,542). SBP: systolic blood pressure; DBP: diastolic blood pressure; HR: heart rate; RR: respiratory rate; GCS: Glasgow Coma Scale; BT: body temperature; ISS: Injury Severity Scale; 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; ED: emergency department; SD: standard deviation.
