Polyp Height and Detectability at Radiologists’ Prospective Interpretation of CTC Images

	Polyps Found at Prospective Interpretation		Polyps Not Found at Prospective Interpretation
	Adenoma	Hyperplastic	Adenoma	Hyperplastic
Height	2.9±1.2 [146]	2.7±1.1 [64]	3.0±1.3 [12]	1.9±1.0 [9]
Height-to-Width Ratio	0.39±0.20 [146]	0.34±0.20 [64]	0.35±0.20 [12]	0.25±0.15 [9]

Heights are in millimeters (mean±st. dev.). Numbers of polyps are in brackets. For adenomas in different groups, p=0.87. For hyperplastics, p=0.07.

Height-to-width ratios are dimensionless. For adenomas in different groups, p=0.46. For hyperplastic polyps, p=0.14).
