Data are presented as mean ± SEM.

^a,b,cValues in the same row that do not share the same superscript letter are significantly different.

*p<.01, **p< .0001.

Model 1: No adjustment; Model 2: Adjusted for HDL-C and LDL-C.

GPx: glutathione peroxidase; HbA1c: glycated haemoglobin; SOD: superoxide dismutase; TAC: total antioxidant capacity.
