Table 2 Performance of diagnostic methods

Parameters	Surgical pathology	Computed tomographic colonography		Colonoscopy
Patients	77	318	^*p-value	318	^*p-value
Polyp ≥10 mm ø	25(32)	27(8)	0.863	23(7)	0.859
Polyps < 10 mm ø but suspicious	49(64)	47(15)	0.863	41(13)	0.859
Non suspicious and < 10 mm ø polyps	3(4)	239(75) ^**	< 0.0001	247(78)^**	< 0.0001

Data are presented as frequency (percentage)
^*Respect to surgical pathology
Lesion ulceration, extramural invasion, and/ or lesion shouldering was considered as suspicious polyp
The Fischer exact test was used statistical analysis
A p < 0.05 was considered significant
^**Significant difference with respect to surgical pathology
