Most important, 22.6 percent of Thompson's case patients (subjects with a head injury) had been involved in collisions with moving automobiles, as compared with only 12.5 and 3.9 percent in each of the two control groups. The subjects with a head injury were also less likely to have fallen onto soft surfaces….
