The quantification data presented are for carbohydrates unless otherwise indicated and are expressed as the mean ± SD, in grams (g). The “app minus reference quantification” columns present the differences (mean ± SD) between the app and reference quantifications and the results of Student’s t-test (p) (results in bold are significant differences). The “Pearson correlation r” columns present the correlation between the app and reference quantifications (results in bold are nonsignificant correlations)
