Figure 2. Association between DNA copy number–associated differentially expressed genes and survival.

Figure 2

A) Hierarchical clustering of an independent dataset of 133 patients using the 95 CNA-associated differentially-expressed gene signature. Expression variances of the genes were summarized by principal components analysis. A hierarchical clustering analysis was performed using the first three principal component (PC) scores; B) Overall survival of the two patient clusters stratified by the 95-CNA-associated differentially expressed signature; C) Cumulative incidence of OSCC-specific death for the two patient clusters.
