|---|---|---|---|---|---|---|---|---|
| TP | TN | FP | FN | Sensitivity (%) | Specificity (%) | Accuracy (%) | ||
| ANN | 277 | 129 | 142 | 5 | 1 | 99.2 | 96.6 | 97.8 |

a
Abbreviations: TP, true positives; TN, true negatives; FP, false positives; FN, false negatives. Sensitivity is calculated as TP/(TP + FN); specificity is TN/ (TN + FP); and accuracy is (TN + TP)/(TN + TP + FN + FP).
b
These strains were not included in the reference database.
