  1. *Propensity score was calculated based on multiple logistic regression model after adjusting for age, sex, hypertension, diabetes, hypercholesterolemia, smoking, clinical presentation, vessel location, percent diameter stenosis, lesion length, pre-intervention fractional flow reserve, and pre-intervention coronary flow reserve.
  2. †MACE included all-cause death, target-vessel MI, and target-vessel revascularization.
  3. CI Confidence interval, HR Hazard ratio, IPW Inverse probability weight, MI Myocardial infarction, MACE Major adverse cardiac events, PS Propensity score.
