Scatter plots of SD−15–240 min-glucose (SD-glucose) and AUC−15–120 min-glucose (AUC-glucose) with time 50% during meal sequence tests (Time50%) were plotted (RF, black circles; FR, white circles; MR, white triangles) for healthy controls (a, b) and type 2 diabetes patients (c, d). The Pearson correlation coefficient (r) and p values were calculated, respectively, as follows: (a) r = −0.526, p < 0.05; (b) r = −0.433, p < 0.05; (c) r = −0.578, p < 0.05; and (d) r = −0.746, p < 0.05
