Linear correlation details of the SWA with fat inclusion and the SWS with fibrosis level. The Spearman’s correlation coefficients r and the p-values are also reported.

Cases	R2 (goodness of fit)	Correlation slope m (as in y=mx+b)	Spearman’s correlation
			r	p-value
All fibrosis cases (F0, F1, F2, F3, F4)	0.555	5.82 (Np/m) / (% fat)	0.75	< 0.001
subgroup 1 (F0, F1)	0.924	8.21 (Np/m) / (% fat)	0.96	< 0.001
subgroup 2 (F2, F3)	0.723	4.26 (Np/m) / (% fat)	0.85	0.0076
subgroup 2 (F3, F4)	0.785	2.68 (Np/m) / (% fat)	0.89	0.0034
All fat cases (6%, 12%, 18%, 24%)	0.874	8.81 × 10−2 $\left(\frac{\text{m/s}}{\text{kPa}}\right)$	0.89	< 0.001
