Notes: Amounts of food were coded as ordinal variables: 1 = do not finish the dish at the first round; 2 = finish the dish at the first round; 3 = take the second round of the dish, no matter they finish it or not. Consumption of vegetables was from the consumption of side dishes. ^a Comparison of medians among treatments using Kruskal–Wallis rank sum tests.*, ** and *** denote significant difference at the 0.10, 0.05 and 0.01 levels, respectively
