Figure 3From: Acute effect of meal glycemic index and glycemic load on blood glucose and insulin responses in humans Serum insulin and plasma glucagon profile after meals differing in glycemic index and meal size. Values are medianand 75th percentile. (∙) high glycemic index; (∘) low glycemic index; (—) large meal size; (----) small meal size. Differences in serum glucose, insulin, FFA and plasma glucagon concentrations were analyzed by Friedman's test and two-tailed Wilcoxon ranked post hoc test. Letters indicate significant difference (p < 0.05) between medians as follows: a, vs ; b, vs ; c, vs ; d, vs ; e, vs ; f, vs Back to article page
