Fig. 4. Time course of changes in plasma retinol (4A), plasma -tocopherol (4B) and plasma malondialdehyde (4C) taken at fasting F, just after the post-breakfast glucose peak BP, just before lunch B3.5, just after the post-lunch glucose peak LP, just after the post-lunch glucose dale LD and 5 hours after lunch L5. Shown are means ± SEM of 23 patients. The horizontal error bars depict the SEM of the time taken to reach the blood glucose peaks at BP and LP and dale LD. P-value denotes the significance of the overall change over time, obtained by repeated measure analysis of variance. * denotes p < 0.05 when contrasted to the value at fasting. denotes p < 0.05 when contrasted to the preceding value.
