Performance of SoTone and SoNoise to Independently Predict ENT Diagnostic Results
| Test type | Sensitivity, %a | Specificity, %b | PPV, %c | NPV, %d | Accuracy, %e |
|---|---|---|---|---|---|
| SoTone | 2 | 50 | 92 | 50 | 88 |
| SoNoise | 42 | 50 | 85 | 11 | 50 |
ENT = ear, nose, and throat; NPV = negative predictive value; PPV = positive predictive value.
Note: Patients consulting ENT specialists were positive on at least 1 test which affects the pertinence of metrics based on negative predictions.
↵a Sensitivity = number of true positive results divided by total number of positive results.
↵b Specificity = number of true negative results divided by total number of negative results.
↵c PPV = number of true positive results divided by the number predicted positive.
↵d NPV = number of true negative results divided by number predicted negative.
↵e Accuracy = number of good predictions divided by the total number of predictions.
