Validation of the constructed molecular subtypes in GSE14520. (A) The NMF clustering consensus map of the validation set (GSE14520) based on the expression of the same gene set as used in TCGA cohort. The molecular subtyping method was consistent with that of the training set. (B) The Kaplan-Meier analyses for the OS (Left) and RFS (Right) of Subtype1 and Subtype2 patients in the validation dataset. P values were generated from Log-rank tests.
