The Brain Injury Screening Questionnaire (BISQ)12 was used to collect data on previous concussions/TBIs. It was an optional, self-administered battery within the PROTECT study, and of eligible participants with sufficient data in the PROTECT study, 4379 individuals did not complete the BISQ and 15 764 did. The baseline characteristics of responders and non-responders are compared in online supplemental table S2 to assess for self-selection bias.
