Figure 6From: CD44 isoforms are heterogeneously expressed in breast cancer and correlate with tumor subtypes and cancer stem cell markers Overall survival in patient subgroups derived from hierarchical clustering of CD44 isoform gene expression data. The 10-year overall survival differed between the four clusters A-D (log rank P = 0.05). The number of patients at risk in each cluster is shown below the time axis.Back to article page
