IPA network 3 (score = 35) clustered 24 (of 35 in the network) of the differentially expressed genes between Xtr vs. Non using genes with ≥2.0-fold expression difference. Genes with ≥2.0-fold expression difference indicated with fold change value. Remaining genes had <2.0-fold expression difference between Xtr vs. Non. Red nodes indicate genes with greater expression in the Xtr vs. Non; green nodes indicate genes with reduced expression in the Xtr vs. Non; white nodes indicate genes that are not differentially expressed, but related to this network. *Transcript represented by multiple probe-sets. Mod, modest responder; Non, nonresponder; Xtr, extreme responder.
