Correlation between the fasting plasma levels of lipid oxidation stress markers and glycometabolism markers, insulin secretion, and insulin resistance during OGTT.

*, #, p<0.05; **, ##, p<0.01; (–), p>0.05 compared with the corresponding value in fasting lipid oxidation stress markers. Marks *, ** and #, ## indicate positive and negative correlations, respectively. ND means not determined.Figure 5 shows the correlation between plasma levels of (10- and 12-(Z,E)-HODE)/LA and HbA1c in all subjects. Fasting plasma levels of (10- and 12-(Z,E)-HODE)/LA significantly increased with increasing levels of HbA1c (p<0.05, Fig. 5). Interestingly, the HbA1c levels of the 2 diabetes individuals (Group D, indicated by arrows) were much higher than the correlation line.
