Comparisons were in the frequency of each mechanism of injury between participants with at least one HI due to IPV and participants with no HIs due to IPV, which were made using χ2 or Fisher's exact test. Cells with a dash in the χ2 column indicate that Fisher's exact test was conducted.
ATV, all-terrain vehicle; CI, confidence interval; HI, head injury; IPV, intimate partner violence; OR, odds ratio.
