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 | VF Induction | Patients having VF induction with shock termination at implant (Implantable defibrillator: Implantable defibrillator to reduce ventricular arrhythmias via shock) | 8 | 836 | OG000 |
| Group 2 | no VF Induction | Patients not having VF induction at implant or during follow-up (Implantable defibrillator: Implantable defibrillator to reduce ventricular arrhythmias via shock) | 4 | 1,284 | OG001 |
