Predominant color of the cortex in sonoelastography with respect to healthy and metastatic LNs
Cortex Group 1 healthy LNs n=165 Group 2 metastatic LNs n=15 p (pairwise comparison)
red (soft) 0% 0% n.a.
yellow 1.2% 0% n.s. (1.000)
green 13.9% 0% n.s. (0.223)
turquoise 64.2% 40.0% n.s. (0.093)
blue (hard) 20.6% 60.0% 0.001
p-value (multivariate analysis) 0.006

The cortex of metastatic LNs is significantly harder and therefore significantly more often described as blue than the cortex of healthy LNs. (n.s. = not significant, n.a. = not applicable, LN = lymph node).
