  1. MACCE major adverse cardiac and cerebrovascular event, MACE major adverse cardiac event, HR hazard ratio CI confidence interval
  2. aHazard ratio was adjusted for age, sex, insurance type, and comorbidities
  3. bHR for coronary artery bypass graft was not calculated due to very low incidence
