Variable	T2D ()	PDM ()	NG ()	^1
Plasma TAC
FRAP (μmol/L)				0.033
TEAC (μmol/L)				0.027
ORAC (μmol/L)				0.019

All values are mean ± SD. ¹One-way ANOVA. Means with the different superscripts in a given row are significantly different at (Tukey’s post hoc test). NS: not significant; FRAP: ferric reducing antioxidant power assay; GPx: glutathione peroxidase; MDA: malondialdehyde; NG: normoglycaemic subjects; ORAC: oxygen radical absorption capacity; PDM: prediabetics; TEAC: Trolox equivalent antioxidant capacity assay; TAC: total antioxidant capacity; T2DM: type 2 diabetes mellitus.
