Measured at 1 week, 4 weeks, and 3 months after stent placement. Migration in proximal direction is denoted as negative values. The accumulated numbers at 3 months and during the subjects’ life span are also shown
Pearson Chi-Square test1 or two-tailed Mann–Whitney U test2 was used for data evaluation. p < 0.05 was considered significant
