question: Compared to 50?g OGTT (A) what was the result of 3 breakfasts (B1: milk and cereals; B2: milk, apple, and chocolate cream-filled sponge cake; B3: milk, apple, bread, and hazelnut chocolate cream) on the 2-hour plasma ghrelin?
context: the repeated measures ANOVA with Greenhouse-Geisser correction resulted significant (p < 0.001) and the Tukey-Kramer post hoc test revealed that B1 (36.2 ± 3.8 mg/dL), B2 (19.6 ± 2.9 mg/dL), and B3 (27.3 ± 4.0 mg/dL) had significantly smaller glucose incremental peaks than A (55.9 ± 6.1 mg/dL) with p values associated to such post hoc comparisons that were p = 0.04, p < 0.001, and p = 0.002, respectively.
