Does Supersonic Shear Wave Elastography Help Differentiate Biliary Atresia from Other Causes of Cholestatic Hepatitis in Infants Less than 90 Days Old? Compared with Grey-Scale US

Table 3

Comparison of the Young’s modulus values in the same group with different ages and in different groups with same age.

Group	all ages		≤30 days		31-60 days		61-90 days
	n	Young's modulus	n	Young's modulus	n	Young's modulus	n	Young's modulus
		value (kPa)		value (kPa)		value (kPa)		value (kPa)
Control	62		29		20		13
non-BA	87		48		28		11
BA	51		20		19		12

compared with control group, P<0.01.
compared with non-BA group, P<0.01.
compared with ≤30 days group, P<0.01.
compared with 31 to 60 days group, P<0.01.
