Fig. 2: Kaplan-Meier survival analysis between the high (N = 53) and low (N = 673) risk breast cancer groups.

For the four breast cancer subgroups determined from the previous aWCluster analysis10, the distinctly poor survival group was denoted as the high risk group and the other three subgroups were merged and denoted as the low risk group. The overall survival rates were significantly different between the two groups (log-rank p = 0.0006).
