The Association between Serum Cytokines and Damage to Large and Small Nerve Fibers in Diabetic Peripheral Neuropathy

Figure 1

The correlation between the serum concentration of IL-6 and sural nerve sensory nerve action potential (SNAP) amplitude (Spearman’s ρ correlation coefficient = −0.085, ; panel (a)) and common peroneal nerve compound muscle action potential (CMAP) amplitude (Spearman’s ρ correlation coefficient = −0.067, ; panel (b)). For both correlations, Spearman’s ρ correlation coefficient turned out to be significant.
