Table 3 Positive predictive value and negative predictive value of liver computed tomography for the detection of high-risk esophageal varices by three observers

	Observer 1	Observer 1	Observer 2	Observer 2	Observer 3	Observer 3	All	All
	Transverse	3 MPR	Transverse	3 MPR	Transverse	3 MPR	Transverse	3 MPR
PPV %	75.8 (25/33)	78.1 (25/32)	73.5 (25/34)	73.5 (25/34)	63.9 (23/36)	77.4 (24/31)	70.9 (73/103)	76.3 (74/97)
P value	0.947		1.000		0.352		0.482
NPV%	97.0 (65/67)	97.1 (66/68)	97.0 (64/66)	97.0 (64/66)	93.8 (60/64)	95.7 (66/69)	95.9 (189/197)	96.6 (196/203)
P value	1.000		1.000		0.710		0.797

P values represent the differences of the positive predicative value and the negative predicative value for transverse images alone and for the three orthogonal MPR images (χ² test and Fisher's exact test). MPR: Multiplanar reformation; PPV: Positive predicative value; NPV: Negative predicative value.
