Clinical outcome numbers are expressed as counts (percentage). Adjusted HRs were calculated using multivariate analysis. All baseline and procedural characteristics with p<0.05 in univariate analysis were entered into the multivariate analysis to calculate adjusted HR's.
MI, myocardial infarction; ST, stent thrombosis.
