Table 2. HULC expression cut-off based on predictive probability of clinical outcome among the OS patients.

Gene	Cut-off*	Sensitivity %	Specificity %	PPV %	NPV %	Accuracy %	AUC
		(CI)	(CI)	(CI)	(CI)	(CI)	(CI)
HULC	0.000048	50.0	73.7	58.3	66.7	64.6	0.48
		(23.0–76.9)	(48.8–90.8)	(27.7–84.8)	(43.0–85.4)	(50.4–76.5)	(0.25–0.70)

*The optimal cutoff was determined as the point at which it simultaneously maximized sensitivity and specificity

PPV: positive predictive value; NPV: negative predictive value. CI: 95% confidence interval.
