1 Sorted by SCC values for the total sample; n—sample size; SCC—Spearman’s correlation coefficient: * p < 0.05; p–significance level of Wilcoxon’s test (for two dependent samples) for differences in means of food consumption frequency (times/day) between the test and the retest; NA–statistical analysis was not performed in this age group due to sample distribution (not enough respondents in a category).
