In the oxidative stress marker panel, only PTGS2 differed between T2DM and controls (p < 0.0001), and comparison of baseline to hypoglycemia in T2DM subjects showed fibroblast growth factor 8 (FGF8) (p < 0.0001) was significantly different, after multiple testing correction. Here, PTGS2 is linked to type 2 diabetes mellitus.
