Fig. 2. Differential effects of 3 doses of Korean red ginseng (KRG) rootlets on postprandial glycemia in a dose-finding study. The line plots and bars in the array represent the incremental change and area under the curve (AUC) for placebo (•) or one of 3 doses of KRG-rootlets—2 g (), 4 g (), 6 g ()—administered 40-min before a 50 g-OGTT in 12 healthy nondiabetic subjects (sex: 9M:3F, age: 29 ± 3 y, BMI: 22.5 ± 1 kg/m²). P-values reported in the base of each plot area are for the main effects of treatment and time and their interactions from repeated measures two-way ANOVA. Data are mean ± SEM.
