^†Categorical variables are represented by the number of animals that fit the demographic characteristic listed in selected variables and the percent of animals that fit the demographic characteristic listed, stratified by exposure group

^‡Continuous variables are represented by a mean value and SE for each exposure group

^§Statistically significant differences between exposure groups are bolded (as calculated by Pearson’s chi-squared test for categorical variables and one-way ANOVA for continuous variables, alpha = 0.05)
