Identification and Validation of a Potential Prognostic 7-lncRNA Signature for Predicting Survival in Patients with Multiple Myeloma

Figure 2

Identification of a 7-lncRNA signature risk model and survival analysis. (a) The distribution of the standard deviation of lncRNAs: red indicates the position of the standard deviation of lncRNA probes whose frequency is greater than 300, the horizontal axis indicates the standard deviation, and the vertical axis indicates the number of probes. (b) The frequency distribution of lncRNA selected by the rbsurv feature a thousand times. The horizontal axis represents lncRNA, and the vertical axis represents the frequency of occurrence. Red indicates that the standard deviation of the lncRNA probe is greater than the median of the overall standard deviation, and green indicates that it is less than the median of the overall standard deviation. (c) Risk score, survival time, survival status, and expression of 7 lncRNAs in the training set. (d) ROC curve and AUC of a 7-lncRNA signature. (e) KM survival curve distribution of a 7-lncRNA signature in the training set.
