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 | Early Intervention | Coronary angiography to be performed as rapidly as possible and within 24 hours after randomization | 153 | 1,593 | OG000 |
| Group 2 | Delayed Intervention | Coronary angiography to be performed after a minimum delay of 36 hours after randomization | 163 | 1,438 | OG001 |

Outcome
- Type
- PRIMARY
- Title
- Composite of Death, Myocardial (re-) Infarction, or Stroke
- Description
- Time frame
- 180 days
- Population
All patients were included in the final intention-to-treat analysis. Event rates in the two groups were estimated with the use of the Kaplan-Meier method. The hazard ratio and two-sided 95% confidence intervals were calculated with the use of a Cox proportional-hazards model.
