Construction of the LMRG signature for predicting overall survival in the training set and validation of it in the test set and the whole set. The Kaplan‒Meier curves estimate overall survival for the low- and high-risk groups based on the risk score in the training set (A), test set (B), and TCGA-BRCA (C); The distribution of risk score, survival status, and the two-gene expression panel in the training set (D), test set (E), and TCGA-BRCA (F); ROCs of LMRGs signature for prediction of overall survival at 1, 3, and 5 years in the train set (G), the test set (H), and the TCGA-BRCA (I). LMRGs, lipid metabolism-related gene signature; TCGA, The Cancer Genome Atlas; TCGA-BRCA, TCGA breast cancer cohort; ROC, receiver operating characteristic curve; AUC, area under the curve.
