Notes: * The five selected nutrition-related school environment characteristics were: fresh fruit, milk, cold drinks containing sugar, sweet snacks or salted snacks can be obtained on the school premises; † Statistically significant difference of mean scores across countries for the indicated round (one-way ANOVA; p < 0.0001); § Statistically significant difference of mean scores between the two rounds for the indicated country (unpaired t-test; p < 0.0001); a,b,c,d,e,f,g,h Within each round (i.e., by column), scores that share the same superscript letter do not statistically significantly differ from each other (Games-Howell post hoc test); –, no participation; COSI, Childhood Obesity Surveillance Initiative; CV, coefficient of variation; SD, standard deviation.
