Relationship between the patient subgroups classified by mRNA expression of PPM1H and VIM and disease-free survival in the discovery data set. (a) Classification of the subgroups with high or low PPM1H mRNA expression; (b) survival analysis between patients with PPM1H-high tumours or PPM1H-low tumours; (c) three patient subgroups defined by PPM1H and VIM mRNA expression; (d) survival analysis among the subgroups defined by the PPM1H/VIM system. The location of the cut lines was defined according to StepMiner analysis
