KEGG pathway classification of differentially expressed genes.

<p>RichFactor is the ratio of DEG numbers annotated in a given pathway term to all gene numbers that were annotated in the pathway term. Greater RichFactor means greater intensiveness. Q-value is the corrected P-value ranging from 0~1, and lower Q-value indicates greater intensiveness. The top 20 pathway terms enriched by the KEGG database are listed in this figure.
