  1. Mean (± SEM) shown. Participant demographics were assessed using a 2-way ANOVA for age, education, participation in collision sports, and previous concussions. Statistical testing of symptom number and symptom severity were performed with a 2-way MANOVA while statistical testing of a HoMC was performed with a χ2 test
  2. HoMC history of multiple concussions, SRC sports related concussion
