PR = Prevalence ratio; CI = Confidence interval
^aTravel by automobile = drive their own car, ride with someone else, or borrow someone else’s car or truck (n = 153, 46% of total sample)
^bTravel by other means = walk, bus, bicycle, ATV/snowmobile, or other means (n = 177, 54% of total sample)
^cAdjusted for age, gender, race, sexual orientation, incarceration, homelessness, years of injection, injection frequency, inject multiple times per sitting, inject heroin, inject cocaine, inject meth, inject speedball/goofball, ever received medication for opioid use disorder
