^a,b,cMean values within a row with unlike superscript letters were significantly different as determined by pairwise comparisons using Tukey's B post hoc test (P < 0·05).

*Student enrolment data collected with NEMS (Nutrition Environment Measures Survey) data.

†Community population density is the population of the city within which the institution is located/city area in square miles according to 2010 census data.

‡ANOVA main effects indicate significant differences by institution size (P = 0·019).

§Pearson χ ² determined a significant difference in the distribution of restaurants assessed by institution size: P = 0·002; χ ² = 16·75, df = 4.
