Metrics used in the study with their descriptions.
| Metric | Description |
| TP | True positives |
| TN | True negatives |
| FP | False positives |
| FN | False negatives |
| Sensitivity | TP/(TP+FN) |
| Specificity | TN/(FP+TN) |
| Precision | TP/(TP+FP) |
| Prevalence | (TP+FN)/(TP+TN+FP+FN) |
| Accuracy | (TP+TN)/(TP+TN+FP+FN) |
| Kappa | (Pobs–Pesp)/(1–Pesp) |
| F-score | (2×precision×sensibility)/(precision+sensibility) |
| McNemar | Exact P value from McNemar test (binomial distribution) |
