Use of P-selectin, total microparticles and D-dimer as dichotomous variables for the prediction of DVT.
| Variables | Threshold value | Sensitivity | Specificity | Accuracy |
|---|---|---|---|---|
| Soluble P-selectin | 0.68 ng/mg TP | 68% | 81% | 74% |
| Total microparticles | 125% (compared to controls) | 50% | 67% | 58% |
| D-dimer | 3 mg/l | 64% | 76% | 70% |
| Combined variables | 73% | 81% | 77% |
