Table 3.

Sensitivity, specificity, and accuracy.

miRNA state
Genuine miRNA Not genuine miRNA
miRNA prediction Positive True positives (TP) False positives (FP)
Negative False negatives (FN) True negatives (TN)
Formulas Sensitivity or true positive rate TP/(TP + FN)
Specificity or true negative rate TN/(FP + TN)
Accuracy (TP + TN)/(TP + FP + FN + TN)
