The number of events for survival analyses (n = 152) and analyses of FFR (n = 115) is indicated in Fig. 1 (number of events for the respective subgroup analyses is indicated in Figs 2 and 3). OS of the entire patient cohort at 1, 3, 5 and 10 years was 96.4%, 91.0%, 87.2% and 62.7%, respectively. Accordingly, DFS, CSS and FFR were calculated: DFS: 84.3%, 60.9%, 44.9% and 15.2%; CSS: 97.8%, 94.9%, 92.3% and 79.7%; FFR (n = 115) at 1, 3, 5 and 10 years was 83.1%, 57.9%, 43.0% and 22.2%, respectively (Fig. 3).
