Figure 2. — Hierarchical clustering and survival analyses of samples in the training dataset. (A) Two-way hierarchical clustering of samples in the training dataset based on the expression levels of the 44 significantly differentially expressed miRNAs yielded 2 clusters, labeled as cluster 1 and cluster 2. Early- and advanced-stage samples are indicated in red and black in the horizontal bar. (B) Kaplan-Meier survival curves of the 2 clusters in A. Survival curves for cluster 1 and 2 are indicated in green and red, respectively.
