Table 5 Definitions of parameters used in evaluating the predictions
| Evaluation | Formula |
|---|---|
| Sensitivity | TP/(TP + FN) |
| Specificity | TN/(TN + FP) |
| Accuracy | (TP + TN)/(TP + TN + FP + FN) |
| Positive predictive value (PPV) | TP/(TP +FP) |
| Overall performance (OP) | (Accuracy + PPV)/2 |
