Models for race-specific effects included 2-way interactions between DUI criminal history, non-DUI criminal history, and race or ethnicity; models for sex-specific effects included 2-way interactions between DUI criminal history, non-DUI criminal history, and sex. Results are adjusted for sex; age; race or ethnicity; number of handguns purchased from 1985 until the index purchase; time elapsed between the most recent DUI and non–DUI related arrest events and the index purchase; census tract population size, population density, proportion of persons aged 20 to 44 years who were aged 20 to 24 years, percentage of males, percentage of Latino individuals, and percentage of black individuals, alcohol outlet densities, and socioeconomic status index; and county population, violent and property crime rates, and firearm suicides as a proportion of total suicides. People with arrests but no convictions for DUI were identified separately in the statistical model and the results are not shown.
Refer to footnote c in Table 2 for definitions.
Overall results are reproduced for comparison.
None of the 13 American Indian purchasers with a DUI conviction were arrested for a firearm-related violent crime; it was not possible to estimate these hazard ratios and confidence intervals.
Non-DUI crimes include other alcohol-related crimes.
