Figure 1 Effects of oral glucose loading alone, (solid circle), or with vitamins C and E, (open circle) on flow-mediated dilatation (FMD; mean ± SE) over 4 h. Vitamins C and E prevented the acute attenuation of FMD seen with glucose loading alone (p = 0.0003 by two-way analysis of variance for response of glucose alone versus glucose with vitamins). *p < 0.05 compared with FMD at baseline (0 h); p < 0.05 compared with glucose with vitamins at 2 h.
