Table 5 Calculated diagnostic accuracy (sensitivity, specificity, positive and negative predictive values, accuracy) results after surgery alone and surgery with additional radiation therapy (XRT), with 95% confidence intervals
Diagnostic accuracy | Surgery alone | Surgery plus XRT | p-value (sig. < 0.05) |
|---|---|---|---|
Sensitivity | 97% (95% CI: 86–100%) | 86% (95% CI: 68–96%) | 0.23 |
Specificity | 96% (95% CI: 94–98%) | 98% (95% CI: 96–99%) | 0.36 |
Positive predictive value | 70% (95% CI: 59–79%) | 78% (95% CI: 63–88%) | 0.27 |
Negative predictive value | 100% (95% CI: 98–100%) | 99% (95% CI: 97–100%) | 0.41 |
Accuracy | 96% (95% CI: 94–98%) | 97% (95% CI: 94–98%) | 0.46 |
