*The six types of injury with the highest percentages are listed.
†Fracture includes fractures of the face, neck, trunk, and extremities but does not include skull fractures.
‡Traumatic brain injury (TBI) includes skull fractures, intracranial injury, and unspecified head injuries.
¶Internal injury includes thorax, abdomen, and pelvic injuries.
§Percentages add up to more than 100 because some children sustained more than one injury.
**Cases in which the age was not known (n = 93) are not reported, which affects percentages.
††Cases in which the gender was not known (n = 299) are not reported, which affects percentages.
