Figure 2

Plasma oxidized LDL (A), erythrocyte glutathione peroxidase activity (B), and plasma MDA (C) excursions during the no vitamin arm (black square), low dose vitamin arm (black circle), medium dose vitamin arm (open triangle), and high dose vitamin arm (open diamond). The range for the standard error of the mean (SEM) for oxidized LDL at all data points was: no vitamin arm = 4.3–5.4, low dose vitamin arm = 4.1–5.1, medium dose vitamin arm = 4.5–5.9, and high dose vitamin arm = 3.2–3.6. The range for the SEM for erythrocyte glutathione peroxidase activity at all data points was: no vitamin arm = 10.4–12.6, low dose vitamin arm = 8.5–12.3, medium dose vitamin arm = 10.0–12.1, and high dose vitamin arm = 9.3–12.9. The range for the SEM for plasma MDA at all data points was: no vitamin arm = 0.026–0.112, low dose vitamin arm = 0.037–0.331, medium dose vitamin arm = 0.040–0.098, and high dose vitamin arm = 0.032–0.166. For each of the markers of oxidative stress, no significant difference was observed between the different dosages of vitamin E supplementation, p>0.05.
