Timing of Early Recurrence
The timing of ER is summarized in Figure 2. In each post-ablation month, the incidence of ER was significantly greater in the Non-CF group. ER occurred in multiple months in 35.1% and in 9.1% of the patients in the Non-CF and CF group, respectively (p < 0.001). The last ER most frequently occurred in the 3rd month in the Non-CF group but in the 1st month in the CF-group (Figure 3).
