Table 4. Comparison of LSMs acquired by STE between successive fibrosis stages.

Distinction	S0–1 (n=35) vs. S2 (n=37)	S2 (n=37) vs. S3 (n=13)	S3 (n=13) vs. S4 (n=17)
Fold change	1.23	1.18	1.28
P value	<0.001	0.020	0.001
AUC (95% CI)	0.74 (0.62–0.83)	0.71 (0.56–0.83)	0.78 (0.59–0.91)

Fold change was calculated as the median ratio in the compared successive fibrosis stage cohort. LSM, liver stiffness measurement; STE, sound touch elastography; AUC, area under the receiver operating characteristic curve; CI, confidence interval.
