Multinomial logistic regression analyses predicting membership classifications by history of TBI and hazardous drinking: either history of TBI or hazardous drinking, separately; no history of TBI or hazardous drinking; co-occurring history of TBI with current hazardous drinking for mental health and conduct behaviour measures, n=3130

No history of TBI or hazardous drinking (n=2082) vs history of TBI or hazardous drinking (n=881)
OR (95% CI)
aOR (95% CI)
History of TBI with hazardous drinking (n=187) vs history of TBI or hazardous drinking (n=881)

  • F—design adjusted Wald F tests; ORs and adjusted ORs (aORs) were calculated using logistic regression. aORs were evaluated while holding fixed values of the complexity of the design, sex and grade.

  • ***p<0.001; **p<0.01; *p<0.05.

  • TBI, traumatic brain injury.
