Calculated by ConductScience from the counts the trial posted to ClinicalTrials.gov.
| Measure | Value | 95% interval, lower | 95% interval, upper | Method | Note |
|---|---|---|---|---|---|
| Risk in group 1 | 0.129 | 0.108 | 0.154 | wilson | |
| Risk in group 2 | 0.146 | 0.128 | 0.167 | wilson | |
| Risk difference, group 1 minus group 2 | -0.0172 | -0.0465 | 0.0133 | newcombe hybrid score | |
| Risk ratio, group 1 over group 2 | 0.882 | 0.708 | 1.1 | log | |
| Odds ratio, group 1 over group 2 | 0.865 | 0.671 | 1.12 | log | |
| Number needed to treat, for one fewer death from any cause on VF Induction than on no VF Induction | 58 | from the risk difference interval | the interval includes no difference |

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) | 108 | 836 | EG000 |
| 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) | 188 | 1,284 | EG001 |
