Fine needle aspiration diagnostic characteristics for determining benign disease

	Benign	Malignant
Sensitivity	0.85	0.52
Specificity	0.76	0.98
Positive predictive value	0.95	0.78
Negative predictive value	0.49	0.93
Diagnostic accuracy	0.83	0.92
ROC area under the curve	0.80 (95% CI: 0.71–0.89)	0.75 (95% CI: 0.63–0.87)

ROC = receiver operating characteristic; CI = confidence interval
