𝑁𝑜𝑡𝑒𝑠. Each superscript letter denotes a subset of quartiles of Healthy Eating Index (HEI) categories whose column proportions do not differ significantly from each other at the alpha = 0.05 level. This option computes pairwise comparisons of column proportions and indicates which pairs of columns (for a given row) are significantly different, applying the Bonferroni correction. Different superscripts represent quartiles that differ at the alpha = 0.05 level. Quartiles of HEI score presented are rounded versions for informational purpose. Actual quartiles were calculated to the 0.001 place. Missing values (𝑛=32) were participants with total energies of either < 500 or > 5000 Kcal. The range of HEI-05 was 19.3–84.1 (based on a possible range of 0–100).
