Design outcomes
Primary
| Measure | Time frame |
|---|---|
| The number of thromboembolic events in the 3-month follow-up period in patients not anticoagulated on the basis of: 1. A non high clinical probability (simplified revised Geneva score) and a normal new age adjusted D-dimer cut-off, or; 2. A PE considered as "unlikely" (simplified wells score) and a normal new age adjusted D-dimer cut-off. | — |
