Efficacy outcomes, including differences between primary and satellite centers cohorts
| Efficacy outcomes comparison | All patients | Primary center | Satellite centers | p |
|---|---|---|---|---|
| Mean follow‐up of 13.5 ± 3.2 months | (n = 80) | (n = 47) | (n = 33) | |
| Freedom from documented atrial fibrillation, after one procedure, with or without antiarrhythmic drugs, no. (%) | 69 (86%) | 43 (91%) | 26 (79%) | 0.19 |
| Freedom from documented atrial arrhythmia, after one procedure, with or without antiarrhythmic drugs, no. (%) | 43 (54%) | 25 (53%) | 18 (55%) | 0.90 |
| Freedom from documented atrial fibrillation, after one procedure or more,a with or without antiarrhythmic drugs, no. (%) | 71 (89%) | 44 (94%) | 27 (82%) | 0.15 |
| Freedom from documented atrial arrhythmia, after one procedure or more,a with or without antiarrhythmic drugs, no. (%) | 58 (73%) | 35 (74%) | 23 (70%) | 0.64 |
Note: Categorical data were compared between primary and satellite centers using χ 2 or Fisher test. All analyses were conducted using R version 4.0.0 (www.r-project.org). A p < 0.05 was considered statistically significant.

On average, 1.3 procedures/patient: 1.3 procedures/patient for reference center and 1.2 procedures/patient for satellite centers.
