^* Clinical outcomes were presented as cumulative incidence (Kaplan-Meier estimates, %) of primary and secondary clinical outcomes calculated. Numbers of total events are presented in parentheses. P values are log-rank p value or Breslow p value.
^† Target lesion failure defined as a composite of cardiac death, myocardial infarction (not clearly attributed to a nontarget vessel), or clinically indicated target lesion revascularization by percutaneous or surgical methods at 3 years.
^‡ Patient-oriented composite outcomes included all-cause mortality, any myocardial infarction (includes nontarget vessel territory), and any revascularization (includes all target and nontarget vessel, regardless of percutaneous or surgical methods).
^§ Subacute stent thrombosis, presented with sudden cardiac arrest which occurred at 6 days after percutaneous coronary intervention.
