Figure 2. Kaplan-Meier curve of mesenchymal transition attractor metagenes in breast cancer dataset.

The mesenchymal transition attractor metagene is most prominent in the early stage of breast cancer. The survival curve of the full dataset is insignificant (left). However, when the samples are restricted to only those at early stage (with no positive lymph nodes and tumor size less than 30 mm), the association between the mesenchymal transition attractor and the survival becomes significant (right), with P = 0.032.
