The unconditional multivariate logistic regression model incorporates all components from the univariate analysis and shows that education remains associated with lower canine seropositivity after adjustment for other model variables. All categorical variables use the lowest category as the referent (i.e., no education, less than one minimum wage). Multivariate model statistics: likelihood ratio test = 18.28, P = 0.0056, df = 6, N = 144.
