Table 5 Logistic regression analysis of frequency of seat belt or harness restraint use when riding in a recreational off-highway vehicle (ROV) in the past 12 months by demographics, by residence type, by frequency of ROV riding, and by whether the participant had been in an ROV crash as reported on a survey by Safety Tips for ATV Riders (STARs) program participants in Iowa schools

From: Recreational off-highway vehicle exposure, safety behaviors and crash experiences among adolescents
