Figure 3. Construction of the risk model in the training and validation cohorts. (A) The distribution of risk score and scatter dot plot shows the correlation of risk score and OS in the training cohort. (B) Kaplan-Meier survival curve suggests that the OS of patients with high-risk score is significantly lower than those with low-risk score in the training cohort. (C) The distribution of risk scores and scatter dot plot of patients with breast cancer based on the ARL prognostic signature in the validation cohort. (D) Kaplan-Meier survival curve suggests that the OS of patients with high-risk score is significantly lower than those with low-risk score in the validation cohort.
