		Histology					Histology
		Positive	Negative	Total			Positive	Negative	Total
ROSE	Positive	34	4	38	S-MOSE	Positive	49	5	54
	Negative	16	6	22		Negative	1	5	6
	Total	50	10	60		Total	50	10	60
	Sensitivity	68%				Sensitivity	98%
	Specificity	60%				Specificity	50%
	Accuracy	66.7%				Accuracy	90%
	PPV	89.5%				PPV	90.7%
	NPV	27.3%				NPV	83.3%

ROSE: rapid on-site cytopathological evaluation, S-MOSE: macroscopic on-site evaluation using a stereomicroscope, PPV: positive predictive value, and NPV: negative predictive value.
