  1. a Deaths from external causes are excluded in the model
  2. b Deaths from internal causes are excluded in the model
  3. 1 Prior to baseline imprisonment
  4. 2Alcohol Use Disorders Identification Test (AUDIT) and Drug Use Disorders Identification Test (DUDIT) measured at baseline
  5. 3 Duration (months) of baseline imprisonment
  6. 4 Adjusted for age and covariates significant in crude analysis
  7. 5 Only age at baseline was significantly associated with death from internal causes and an adjusted model was thus not run for this group
