Summary statistics of the gene expression profile of 9,835 samples in TCGA pan-cancer atlas.

(A) The density plots represent the sample distribution of observed z-scores of 10 genes. (B) The density plot and boxplot represent the sample distribution of observed z-scores of 16,323 genes. (C) The pie chart shows the proportion of the Pearson correlation values of 16,323 genes. All the expression values are log-transformed and z-transformed across cancers. The median expression values of samples across cancers are used for summary statistics. (TIFF)
