| Relapse-free patients | Patients with relapse | |
|---|---|---|
| Relapse-free predicted | A = True Positive | B = False Positive |
| Relapse predicted | C = False Negative | D = True Negative |
Sensitivity=A/(A+C); Specificity=D/(B+D); Accuracy=(A+D)/(A+B+C+D)
Positive Predictive Value=A/(A+B); Negative Predictive Value=D/(C+D)
