Figure 3From: Integration of gene expression, clinical, and epidemiologic data to characterize Chronic Fatigue SyndromeFunctional categories of the 117 genes selected by SAM program. These genes are differentially expressed and segregate the gradual from sudden onset of fatigue CFS subjects. Red bars represent the 98 genes for which expression was lower in gradual onset subjects; the green bars represent the 19 genes that had increased expression in the gradual onset group. Genes may be classified in more than one functional group.Back to article page
