  • Variables adjusted for in both multivariable analyses along with the reference group: altered mental status (reference = no), acting normally per parent (reference = yes), history of loss of consciousness (reference = no), history of vomiting (reference = no), any scalp hematoma (reference = no), other traumatic scalp findings (reference = no), palpable skull fracture (reference = no), clinical signs of basilar skull fracture (reference = no), amnesia (reference = no), age (reference = >10 y), time from injury to ED evaluation in hours (reference = >4 h).

  • ciTBI, clinically-important traumatic brain injury; CT, computed tomography; OR, odds ratio; TBI, traumatic brain injury.
