Lower values of superoxide dismutase (SOD) enzyme activity, lymphocyte (LYM), mean cell haemoglobin (MCH), mean cell haemoglobin concentration (MCHC), monocyte (MON), mean platelet volume (MPV), and platelet distribution width (PDW) were related with stroke, whilst SOD enzyme activity, LYM, and MCHC were significant predictors of stroke. Here, SOD1 is linked to Stroke.
