Relationship between the dispersion slope (DS) and liver stiffness measurement (LSM) in the control group (n = 10) and patients with FALD (n = 27).
The correlation efficient (r) and P-value were calculated using Spearman’s rank correlation coefficient (a). Relationship between the dispersion slope (DS) and central venous pressure (CVP) in the control group (n = 10) and patients with FALD (n = 27) (b). DS, dispersion slope; LSM, liver stiffness measurements; CVP, central venous pressure.

Correlation between DS or LSM and different parameters in Fontan patients.
Fig 3.
DS and LSM distribution for different groups.
The median DS in the control, non-significant fibrosis, and significant fibrosis groups was 9.35, 12.55, and 17.64 (m/s)/kHz, respectively (a). The significant fibrosis group showed significantly higher DS than the non-significant fibrosis group. The median LSM in the control, non-significant fibrosis, and significant fibrosis groups were 5.05, 10.80, and 12.60 kPa, respectively (b). There were no significant differences in LSM between the non-significant fibrosis and significant fibrosis groups.

Receiver operating characteristic curve for SWD and 2D-SWE in the diagnosis of significant fibrosis.
The AUROC for diagnosing significant fibrosis was 0.903 and 0.734 for SWD and 2D-SWE, respectively. The differences between SWD and 2D-SWE were significant. AUROC, area under the receiver operating characteristic curve; SWD, shear wave dispersion; 2D-SWE, two-dimensional shear wave elastography.
