Figure 2From: Oral tongue cancer gene expression profiling: Identification of novel potential prognosticators by oligonucleotide microarray analysis Hierarchical clustering of tumor (T), N = 31. A; and normal (N), N = 26. B cluster sets based on the complete panel of 12,000 genes. Horizontal distance represents the correlation of the samples to one another. The numbers at each node represent frequency of the shown pattern using 1,000 iteration bootstrap resampling.Back to article page
