Survival and Event Analysis:
The Kaplan-Meier method was used to estimate the fraction of patients
with event status at each follow-up interval. Survival analysis end
points were arrhythmia (AF/AT) recurrence. Follow-up time was calculated
from the date of AF ablation to the most recent EKG or ambulatory
monitor analysis. Log-rank testing was used to compare differences in
survival or in the above clinical events between patient groups.
Statistical calculations were performed using The R Project 3.6.0.
