The same result was still obtained after stepwise adjustment for important variables such as age, sex, education level, NIHSS score, hypertension, diabetes, coronary heart disease, atrial fibrillation, history of smoking and alcohol consumption, TG, TC, HDL-C, LDL-C, Hb, and FBG (OR, 6.20; 95% CI, 2.10–18.33; p = 0.001) (Table 3). Here, GSTM1 is linked to diabetes mellitus.
