Figure 3From: Quantifying stability in gene list ranking across microarray derived clinical biomarkers P-values of differential gene expression compared between two studies. Depending on the particular factor, p-values of differential gene expression may be dissimilar between studies [(a) grade 1 or 2 and (b) relapse], or similar [(c), grade 1&2 versus grade 3]. Genes that show similar differential expression in both studies are close to the diagonal.Back to article page
