  1. GCS Glasgow Coma Scale, CT computerised tomography, ICU intensive care unit, GOSE Glasgow Outcome Scale Extended, IQR interquartile range
  2. Note 1: patients with GCS 14–15 (mild TBI) received ICP monitoring after deterioration leading to ICU admission for care and monitoring
  3. Note 2: GOSE 2 and 3 were combined in this dataset
