VEGF/Sema expression signatures predicting biochemical recurrence (BCR). a-b: PLS-DA scores/loadings plots for the TCGA (a) and GSE21034 (b) datasets. The training accuracies and the discriminant line separating the two classes are displayed c-d: Survival curves show prognostic significance of VEGF/Sema signatures in the TCGA (c) and GSE21034 (d) datasets. The p-values are from log rank tests of the Kaplan-Meier survival estimators for each group
