Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Left Atrial Ablation | All patients randomized to the ablation group were required to undergo left atrial pulmonary vein isolation. The addition of ancillary ablation techniques including linear, ganglion plexus, and electrogram-based approaches were left to the discretion of the investigators. | 24 | 1,108 | OG000 |
| Group 2 | Rate or Rhythm Control Therapy | All patients randomized to drug therapy, were treated with standard rhythm and/or rate control drugs selected in accordance with contemporary guidelines, according to investigator discretion. | 27 | 1,096 | OG001 |
