Comparison of AUROC, positive predictive value, sensitivity, specificity of serum GP73, AFP level and abdominal ultrasound in the diagnosis of HCC

	PPV	AUROC	Sensitivity	Specificity
GP73		0.79- 0.94	69% - 95%	70%- 93%
AFP	61%~83%		30%-95%	28%- 96%
Abdominal ultrasound	14%~73%		71%- 78%	90% -93%

GP73, Golgi protein-73; AFP, Alpha-fetoprotein; AUROC, area under the receiver operating curve; PPV, positive predictive value.
