A masked independent diagnostic and assessment committee evaluated all clinical and imaging data as well as the treatment. The committee consisted of 2 researchers who received training before the commencement of the current study and were not involved in the provision of clinical care to patients. The primary endpoint of this research was the 6-month Glasgow Outcome Scale (GOS), which categorized the results into 5 levels: grade 5 indicated a positive recovery, grade 4 indicated a minor disability, grade 3 indicated a severe disability, grade 2 indicated a continuous vegetative state, and grade 1 indicated death.
