‘Unknown’ incidents included trauma related incidents such as head injuries where information regarding the incident is missing.

Patients with multiple injured body regions (e.g. Pelvis/Spinal Trauma) were listed in all identified body regions and hence percentages add to greater than 100.

Patients considered ‘dead pre arrival’ and non-trauma patients excluded.
