*
delineates statistical significance at Benjamini-Hochberg correction threshold of p<0.025 for main comparisons (age group*sex, age group, sex) and p<0.023 for regression control comparisons (race, education, PMH psychiatric, mechanism, LOC, GCS, CT, polytrauma). B = mean difference; CI = confidence interval; CT = computed tomography; ED = emergency department; GCS = Glasgow Coma Scale; LOC = loss of consciousness; PCLC = Post-Traumatic Stress Disorder Checklist-Civilian Version. PMH = prior medical history; RPQ13 = Rivermead Postconcussional Symptoms Questionnaire-13 Item
