  1. Using the Cox proportional hazards model to calculate the Hazard Ratios of four BP parameters that was standardized for the risk of stroke incident. Adjusted variables: age (years), sex, ethnicity, BMI, HR, current smoking, current drinking, diabetes mellitus, anti-hypertension drug treatment, TC, TG, HDL-C, LDL-C
  2. BP blood pressure, SBP systolic blood pressure, DBP diastolic blood pressure, PP pulse pressure, MAP mean arterial pressure, BMI body mass index, HR heart rate, TC total cholesterol, TG triglycerides, HDL-C high-density lipoprotein cholesterol, LDL-C low-density lipoprotein cholesterol
