Table 5 Adjusted multinomial logistic regression associations between houselessness and the frequency of SSP use in the prior 30 days among Rural Opioid Initiative PWID and used an SSP at least once in the prior 30 days (n = 972)

  1. Bold indicates statistically significant at p < 0.05
  2. SSP Syringe service program, PWID people who inject drugs, aOR adjusted odds ratios, CI confidence interval
  3. Multivariable regression was performed excluding participants who reported ‘don’t know how close an SSP is’ (n = 5) because model would not converge due to small cell sizes
  4. aReference period: prior 6 months
  5. bReference period: prior 30 days
