Figure 2From: Cross-study analysis of gene expression data for intermediate neuroblastoma identifies two biological subtypes Hierarchical clustering of the expression data for the significant genes in advanced stage MYCN amplified tumors versus low stage non-amplified tumors. (A) Oligonucleotide data. (B) cDNA data. The colored bars at the top of the figure denote the values of the following clinical variables: Status: black – unfavourable outcome, grey – favourable outcome; Age (at diagnosis): black – older than one year, grey – younger than one year.Back to article page
