Falls, AHT (Abusive Head Trauma), and MVCs (Motor Vehicle Crashes) were not mutually exclusive mechanisms of TBI (Traumatic Brain Injury); 2 children with AHT and 6 children with falls were also coded as having MVCs; 20 children were coded as having both AHT and falls. Column percentages my not add up to 100% due to rounding.
