†
P-values for significant differences by unidimensional measures of structural racism are based on the Kruskal-Wallis test with “low” as a reference group.
‡
P-values for significant differences by multidimensional measures of structural racism are based on the Kruskal-Wallis test with Class A as a reference group.
