Correlation between NXScores and gene expression levels. The 19055 genes were first ranked according to increasing NXScore for the whole gene (TSS to end of 3'UTR), and the sorted list was divided into (a) 5 and (b) 10 groups. The mean value of the median expression level for the genes in each group was plotted. The graph shows that NXScores are positively correlated with gene expression level except at the very high NXScores, where expression levels decrease.
