  • Abbreviations: OR = Odds Ratio, CI = Confidence Interval

  • a Outcome adjusted for by sex

  • b Outcome adjusted for by age

  • c Outcome adjusted for by marital status

  • d Outcome adjusted for by race/ethnicity

  • e Outcome adjusted for by veteran status

  • f Outcome adjusted for by education and employment

  • g Analyses limited to those who replied yes to lifetime traumatic brain injury with loss of consciousness question

  • h Before rounding, the confidence interval was 1.01 – 1.78, so it is included here and the OR is considered significantly different than 1.0

  • i Results are P < 0.05

  • -Indicates no modeling was conducted due to lack of significance in the bivariate model

  • indicates no modeling was conducted due to lack of significance in the primary outcome of lifetime traumatic brain injury with loss of consciousness
