accuracy of thyroid sonography in predicting thyroid malignancy
| n=107 | Histology + Cytology | |
|---|---|---|
| Malignant | Benign | |
| Sonography | ||
| Malignant | TP=2 | FP= 0 |
| Benign | FN=0 | TN=105 |
TP=True positive, TN=True negative, FP=False positive, FN=False negative, Sensitivity= TP / (TP + FN) = 100%, Specificity= TN / (FP + TN) = 100%, Prevalence of malignancy = 1.87%, Positive Predictive Value = TP / (TP + FP) = 100.00%, Negative Predictive Value = TN/(FN + TN) = 100.00%,Accuracy= (TP + TN)/(TP + TN + FP + FN) = 100%
