Traumatic brain injury (TBI) remains a major public health problem globally. In the United States the incidence of closed head injuries admitted to hospitals is conservatively estimated to be 200 per 100,000 population, and the incidence of penetrati

The power of clinical trials depends mainly on the choice of the primary outcome measure, the statistical test, and the sample size. The most widely used outcome measure has been the five-category Glasgow Outcome Scale (GOS). Contrary to intuition, w

The interim analyses based on group sequential procedures are not convenient if the response time relative to the patient accrual rate is long. Since in most trials patients are accrued and randomized continuously, the response data from those alread
