Table 3 The relationship between the number of points on the Wells score threshold equal to zero points and confirmed episodes of DVT
Threshold on Wells scale = 0 | Thrombosis | Without thrombosis |
|---|---|---|
Number of points on the Wells scale: >0 | 59 | 343 |
Number of points on the Wells scale: ≤0 | 1 | 645 |
Sensitivity: 98.33% | Positive predictive value: 14.68% | |
Specificity: 65.28% | Negative predictive value: 98.85% | |
