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

From: Diagnostic value of MRI for detecting recurrent soft-tissue sarcoma in a long-term analysis at a multidisciplinary sarcoma center

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
