40-gene signature φ ⁽⁴⁰⁾_IL4 for ovarian cancer anchored upstream by IL4 is robustly associated with survival. a Clustered heatmap of the mRNA signature φ ⁽⁴⁰⁾_IL4 realized in the 291-sample training data set. b KM plots of patients in training data set with prognostic scores in the top and bottom quartiles based on the eigen-survival model based on the realization of φ ⁽⁴⁰⁾_IL4 in 291-sample discovery data set. c Clustered heatmap of φ ⁽⁴⁰⁾_IL4 realized in the 99-sample test data set. d KM plots of patients in unseen test data set with prognostic scores in the top and bottom quartiles. The prognostic scores for the test patients were obtained by projecting the realization of φ ⁽⁴⁰⁾_IL4 in the test data onto the eigen-survival model for φ ⁽⁴⁰⁾_IL4 derived from the discovery data set (green arrows)
