Table 2. . Twenty four-hours post-treatment quantitative ultrasound mean spectral and texture values for the most significant features demarcating complete responders from partial responders.

Parameter	p-value	CR (mean ± SEM)	PR (mean ± SEM)
ΔSI-ENE	0.044	0.002 ± 0.001	-0.004 ± 0.030
ΔSAS-HOM	0.021	0.001 ± 0.002	-0.035 ± 0.030
ΔASD-COR	0.056	0.010 ± 0.008	-0.047 ± 0.038

Bolded parameters demonstrate statistical significance. Other features approach near significance.

ASD: Average scatterer diameter; CR: Complete responders; COR: Correlation; ENE: Energy; HOM: Homogeneity; PR: Partial responders; SAS: Spacing among scatterers; SEM: Standard error of the mean; SI: Spectral intercept.
