After adjusting for demographic information (age and gender), medical history (hypertension, coronary heart disease, hyperlipidemia, and diabetes), main laboratory data (WBC, neutrophil percentage, TG, VLDL, PLT, HDLC, RBC, and HGB), and other variables (BMI>30 and former/current drinking), the significant associations between ERCC1 rs3212986 polymorphism and ischemic stroke susceptibility were also obtained in the recessive model (OR = 2.015, 95% CI = 1.087–3.704, P = 0.026), as shown in Table 2. This evidence concerns the gene ERCC1 and hypertensive disorder.
