Comparison of cumulative stent patency in patients with and without residual stenosis after stent placement. The black plot shows the cumulative stent patency rate in patients with residual stenosis after stent placement. The gray dotted plot shows the cumulative stent patency rate in patients without residual stenosis after stent placement. The vertical lines on the gray plot represent censoring. The figures at the bottom count the cumulative number of patients at risk, censored, and with stent occlusion
