Note: HEI scores are expressed as a percentage of maximum possible scores. Estimates are means and standard errors, or medians and (interquartile ranges) where specified by ∞; * One-way ANOVA and Kruskal-Wallis for non-parametric variables; superscript letters indicate a statistically significant difference (adjusted p < 0.05). a Comparison between this group and majority white. b Comparison between this group and majority black. n.a. = given the lack of variation in the mean scores for dairy across subgroups, statistical testing was not performed.
