Comparisons between tertiles were performed by general linear model.

Lower, intermediate and higher tertiles were calculated on the entire sample (1292 subjects enrolled in the study) and were referred to the distribution of the single cytokine. Mean ± S.D. of nerve conduction velocity were reported according to tertiles of distribution of every Cytokine.

F and p value adjusted for age (years), sex and their interaction.
