		KU-F40 system
		Positive	Negative	Total
FECT	Positive	12	9	21
	Negative	6	984	990
	Total	18	993	1,011
Accuracy: 98.5% (95% CI, 97.5–99.2) Sensitivity: 57.1% (95% CI, 34.0–78.2) Specificity: 99.4% (95% CI, 98.7–99.8) PPV^a): 29.9% (95% CI, 15.0–50.7) NPV^a): 99.8% (95% CI, 99.7–99.9)

^a)PPV and NPV were adjusted based on an institutional prevalence of 0.45%.
Abbreviations: FECT, formalin–ether concentration technique; CI, confidence interval; PPV, positive predictive value; NPV, negative predictive value.
