Kaplan-Meier estimated disease-free survival for the validation set. p-values for tests between groups were p=0.099 (Log-Rank) and p=0.028 (Wilcoxon). Grouping was done according to overexpression of ≥ 4 motility genes or/and TGF-β1. No overexpression of ≥ 4 motility genes or TGF-β1 = group 0 (red). Overexpression of ≥ 4 motility genes or TGF-β1 = group 1 (green). Overexpression of ≥ 4 motility genes and TGF-β1 = group 2 (blue).
