Table 2b:
Sensitivity and specificity of PIV score and ability to predict R1 resection status. PIV=Predictive index value, R0=no gross residual disease, R1=any gross residual disease, PPV=positive predictive value, NPV=negative predictive value.
Laparoscopic PIV score | R0 | R1 | Sensitivity (%) | Specificity (%) | Accuracy (%) | PPV | NPV |
---|---|---|---|---|---|---|---|
< 8 | 117 | 20 | 48.7 | 71.3 | 67.0 | 28.8 | 85.4 |
≥ 8 | 47 | 19 |
