All data are presented in mean ± standard deviation (minimum – maximum, median). RTA: road traffic accidents which include motor vehicle accident, motorcycle collision, and motor vehicle pedestrian accident. LOC: Loss of consciousness. RPQ: Rivermead Post-Concussion Symptoms Questionnaire. Cognition measures and PROMIS data are presented as normalized T-scores (mean of 50, SD = 10) corrected for age, sex, education, and race/ethnicity in the general population.
