Statistical results for CT parameters according to group comparisons

CT parameter	Lipid-rich adenomas vs non-adenomas	Lipid-poor adenomas vs non-adenomas	Lipid-rich adenomas vs lipid-poor adenomas
Size (mm)	<0.001	<0.001	0.005
Unenhanced attenuation (HU)	<0.001	<0.001	<0.001
APW (%)	<0.001	<0.001	0.354
RPW (%)	<0.001	<0.001	<0.001

APW, absolute percentage washout ratio; HU, Hounsfield unit; RPW, relative percentage washout ratio.

The p value levels are for group comparisons by using Mann-Whitney U test.
