Data are presented as median (interquartile range) for continuous variables and n (%) for categorical variables. The Chi-square or Fisher exact test for categorical variables and a Mann-Whitney U test for continuous variables. ,†,‡,§Analyses of pre- and post-procedure TIMI flow were compared using the Wilcoxon signed-rank test in each group. BVS, bioresorbable vascular scaffold; DES, drug-eluting stent; MV, main vessel; SB, side branch; BC, balloon catheter; TIMI, thrombolysis in myocardial infarction.
