Note: TBI = traumatic brain injury; OI = orthopedic injury; SD = standard deviation; NISS = New Injury Severity Score; GCS = Glasgow Coma Scale; NA = Not applicable; GCA = General Cognitive Ability standard score.
a
Injuries due to “other” causes included those related to sports and recreation, rough-housing, and falling objects.
b
Administered at the initial assessment.
