  1. Demographic data in 228 propensity-matched patients with severe traumatic brain injury (TBI) subjected to two different blood glucose targets: 3.5 to 6.5 mmol/l versus 5 to 8 mmol/l. AIS, abbreviated injury score; CT, computed tomography; EDH, epidural haematoma; GCS, Glasgow Coma Scale; ICP, intracranial pressure; ICU, intensive care unit; ISS, injury severity score; SDH, subdural haematoma; tSAH, traumatic subarachnoid haemorrhage; BP = blood pressure.
