Note: A logistic regression analysis can analyze the effect of different factors that influence a dependent variable (in this case, whether or not the person drove after consuming at least two drinks in the preceding hour, at least once in the 12 months preceding the survey) while isolating the effect of other factors. The result is given by the odds ratio, which is calculated in relation to the reference category. For example, Model 2 indicates that a male, compared with a female (reference category) with exactly the same characteristics, was 6.37 times more likely to have reported driving after having consumed at least two drinks in the preceding hour, at least once in the 12 months preceding the survey.
