Time to stent dysfunction. a Entire cohort. The median time to stent dysfunction was not reached (95% CI, 35.6-not applicable) and cumulative incidence of stent dysfunction was 17.5 and 27.9% at 6-months and 1-year, respectively; b Comparison between patients who showed a response (dotted line) and those who did not (solid line). Cumulative incidence of stent dysfunction in responders (n = 21) and in non-responders (n = 68) was 9.5 and 19.1% at 6 months, and 19.0 and 27.9% at 1-year, respectively (p-value = 0.69); c Comparison between responders (dotted line) and non-responders (solid line) among patients who received a combination regimen as the first-line treatment. Cumulative incidence of stent dysfunction in responders (n = 12) and in non-responders (n = 7) was 0 and 42.9% at 6 months, and 8.3 and 57.1% at 1-year, respectively (p-value = 0.009)
