Figure 3From: A comparison of sex-specific immune signatures in Gulf War illness and chronic fatigue syndromeCytokine signatures separating illness groups in female subjects. Immune cytokine expression patterns separating of female GWI, CFS and healthy control subjects identified using a step-wise selection method across all time points (rest, peak activity, and recovery). Red arrows indicate a negative contribution, vice versa for black arrows. Arrow line thickness is proportional to the magnitude of standardized canonical coefficients. While decreased IL-23 expression in the context of increased IL-5 levels provided strong separation of GWI from healthy controls the signal for CFS was much weaker and required relaxation of the constraints on cross-correlation between cytokines.Back to article page
