Univariate and multivariate Cox regression analysis for risk factors associated with DFS (months) in Paul Brousse validation set.

DFS, disease free survival; HR, hazard ratio; CI, confidence interval.aOnly showing factors with p≤0.05 as well as Gene signature prediction.bMultivariate model includes factors with p≤0.05 in univariate analysis (Neoadjuvant chemotherapy and Stage primary tumor) as well as Gene signature prediction.cP values were calculated with the use of log-rank test.dTNM stages 1 and 2 versus 3 and 4.
