[1] The index Glasgow Coma Scale (GCS) score is the highest reliable GCS score documented before randomization.The GCS is scored between 3 and 15, 3 being the worst, and 15 the best. A score of 13 or higher correlates with a mild brain injury, 9 to 12 is a moderate injury and 8 or less a severe brain injury.

  Limitations and Caveats

Limitations of the study, such as early termination leading to small numbers of participants analyzed and technical problems with measurement leading to unreliable or uninterpretable data
The trial was stopped early for futility with respect to the primary outcome.
