NABIS:HIIR was a randomized clinical trial conducted in patients with severe brain injury, age 16-45. Patients were randomized to standard treatment at normothermia or to standard treatment with moderate hypothermia (32.5-34C for 48 hours). An intent to treat analysis was used with the primary outcome measure as the Glasgow Outcome Scale at six months after injury. GOS is dichotomized into good outcome (Good Recovery/Moderate Disability) and poor outcome (Severe Disability, Vegetative, Dead).
