^*All characteristics were included in one model.

^**Overall p-values are Wald F-tests for variables with more than one category.

^***ORs for knowledge and self-efficacy are for a one-item increase in score. Since both knowledge and self-efficacy were transformed to be between 0% and 100%, the presented results are equivalent to a 7.14% increase in knowledge and a 9.09% increase in self-efficacy.
