Summary of results of studies informing sensitivity and specificity of tests for diagnosis of recurrent DVT
| Test . | No. of participants (studies) . | Sensitivity (95% CI) . | Specificity (95% CI) . | Quality of evidence . |
|---|---|---|---|---|
| D-dimer for low PTP, proximal ultrasound for low PTP with positive D-dimer and high PTP | 105 (1) | 0.97 (0.88-0.99) | 0.99 (0.86-1.00) | Low* |
| Proximal ultrasound | 205 (1) | 0.91 (0.80-0.96) | 1.00 (0.95-1.00) | Low† |
| Serial ultrasound | 205 (1) | 0.96 (0.86-0.99) | 1.00 (0.95-1.00) | Low† |

Certainty in evidence was downgraded for imprecision given the small population size from the 1 recurrent lower extremity DVT study identified for analysis.
