| Methods |
RCT comparing aspirin plus clopidogrel versus clopidogrel alone in atherosclerotic peripheral arterial disease. |
| Data |
2161 patients were randomised (1080/1081, respectively in each treatment group). |
| Comparisons |
Onsite assessment (non blinded local investigator) versus assessment by an AC blinded to allocated treatment. |
| Outcomes |
The primary outcome selected was a composite outcome of myocardial infarction, stroke, or death from cardiovascular causes. |
| Notes |
The study was identified because it was included in a pooled analysis of 10 RCTs (Pogue 2009). Data related to the number of events in each treatment group resulting from onsite‐assessor and AC assessments were extracted from this meta‐analysis on the primary outcomes of the included studies. |
