  1. PIR, Pelvic Injury Register; TR, TraumaRegister DGU®; ISS, Injury Severity Score; BP, blood pressure on arrival in the emergency department; Hb, haemoglobin on arrival in the emergency department. The exact match of the records was defined as the Gold Standard, but also minor discrepancies according the above-mentioned criteria were tolerated. The low completeness of 73 records of the initial BP and Hb is due to the fact that in the PIR these both parameters are only mandatory for complex pelvic injuries.
