The 4-lncRNA signature of BC (ADAMTS9-AS1, AL391421.1, LINC00491, and LINC00536) for the outcome. a The survival differences between the high-risk and low-risk groups were determined by the log-rank test (P = 2.18E−04). b ROC curves demonstrated that the area under receiver operating characteristic (AUC) of 4-lncRNA model was 0.696, which exhibited the risk score
