From: Cytokine expression profiles in white blood cells of patients with small fiber neuropathy
Correlation analysis between WBC cytokine expression profiles and pain intensity in SFN patients. The scatter plots show the gene expression of a IL-2, b IL-8, and c TNF in correlation to the pain intensity (determined on a NRS: range 0 = no pain; 10 = maximum pain imaginable) of SFN patients. Gene expression of IL-2 and current pain intensity correlated negatively in SFN patients (a), while no correlation was found for IL-8 (b) and TNF (c). Numbers of samples investigated: SFN patients = 52; IL− interleukin, NRS numeric rating scale, TNF tumor necrosis factor-alpha. *p < 0.05
