All percentages represent column percentages.
*The “other” diagnosis category includes internal organ injury and concussion.
†The coefficient of variation for this result was slightly above 30, and thus marginally unstable.
‡The “unknown” body region and “traumatic brain injury” category had coefficients of variation substantially greater than 30, therefore only unweighted counts are presented.
