Identification and construction of NMIBC progression-related 13-mRNA classifier. (A) The heat map of the expression levels of 73 differentially expressed genes in the training dataset. (B) LASSO coefficient profiles of the 47 prognosis-associated mRNAs. Ten-time cross-validation was exhibited for tuning parameter selection and a vertical line was drawn at the value of the minimal λ used for establishment of 13-mRNA classifier. (C) The optimum cut-off value of the gene signature based risk scores was produced using the X-tile program in the GSE13507 training cohort. Red shows inverse association, while green indicates direct association between risk score and progression-free survival.
