Figure 1. Race/Ethnicity as an Effect Modifier in the Association between Perceived Walkability and Body Mass Index Note:
The estimated means (adjusted for all the other covariates) of body mass index along the perceived walkability scale is depicted by race/ethnicity. All estimates were statistically significant (p<0.05). While the estimates appear to have a strong magnitude for American Indian/Alaska Native and Non-Hispanic other race persons, those samples are considerably smaller. The 95% confidence intervals are not shown as they would obscure the interaction lines.
