  1. aOrdered logistic regression predicting the relative odds of being in the next highest quintile of daily vegetable variety per one unit increase in the predictor variable. For dichotomous predictor variables, the referent group represents individuals who responded negatively to the survey question. For nominal predictor variables (education and food security status), the referent group represents individuals in the next less favorable category as defined in subsequent footnotes
