Table 2. Summary of liver stiffness measurements with STE and SSI.

System	LSVs (kPa)†	IQR/M (%)†	Median-centered COV (%)	ICC for intrasystem agreement‡
STE (Mindray)	9.93±5.21	8.41±5.36	65.2	0.94 (0.937–0.943)
SSI (Aixplorer)	9.69±6.18	5.50±3.62	86.5	0.984 (0.984–0.985)

^†, data are expressed as means ± standard deviations; ^‡, 95% confidence intervals of ICC are in parentheses. STE, sound touch elastography; SSI, supersonic shear imaging; LSV, liver stiffness value; IQR, interquartile range; M, median; COV, coefficient of variation; ICC, intraclass correlation coefficient.
