  1. HRs are adjusted for age, gender, race/ethnicity, ischemic stroke sub-type, baseline stroke severity, baseline glucose, baseline diastolic blood pressure, treatment assignment, smoking status, alcohol use, history of hypertension, and history of previous stroke
  2. RERI Relative excess risk due to interaction, AP Attributable proportion due to interaction
