Evaluation of exosome-associated lncRNA risk model in training set and validation set. (A,B) Kaplan–Meier survival curves for BC patients in training set (A) and validation set (B), shown that the OS of the low-risk groups were significantly higher than the OS of the high-risk groups, respectively (p = 1.017E−07 and p = 4.375E−03, respectively). (C,D) ROC curve analysis of the accuracy of the model to predict patient prognosis at 2, 3 and 5 years in the training set (C) and the validation set (D). The distribution and median value of the risk score in training set (E) and the median risk score of training set was set as the cut-off value of high and low risk groups in validation set (F).
