* Logistic regression analysis on 6-month return to work at full level. Statistically significant (p < 0.05) difference compared to the ‘only PC group’ after adjusted for age, sex, educational level, psychiatric history, and Injury Severity Score. 1 No/mild symptoms: RPQ < 16 and PCL-5 < 33. 2 Severe PC symptoms, no PTSD: RPQ ≥ 16 and PCL-5 < 33. 3 Severe PC and PTSD symptoms: RPQ ≥ 16 and PCL-5 ≥ 33. 4 PTSD, no severe PC symptoms: RPQ < 16 and PCL-5 ≥ 33. 5 20 missing values (2.6%). Abbreviations: PC = post-concussion, PTSD = post-traumatic stress disorder.
