Genome wide prognostic analysis results. a A volcano plot showing the genome wide prognosis analysis results. The vertical and horizontal axis respectively represent the –log10 (p) and regression coefficient value (coef) got from the Coxph survival analysis. Each data point represents the Coxph analysis result of one gene in the mRNA level. Coef < 0 means hazard ratio (HR) < 1 and coef > 0 means HR > 1. Strictly, only genes with p < 0.01 and coef > 0.2 were regarded as unfavourable for prognosis while genes with p < 0.01 and coef <− 0.2 were regared as favourable. b The number of significant favourable and unfavourable genes. c Survival curves for examples of favourable and unfavourable genes
