Correlation analysis.

<p>A Pearson correlation analysis was performed on fold-change values of 123 differentially expressed genes that were retrieved after comparing ours and Beissbarth <i>et al</i> datasets <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0031798#pone.0031798-Beissbarth1" target="_blank">[8]</a>. A correlation coefficient of r = 0.885 shows a high correlation between both datasets.
