IL31 and atopic eczema: The mean IL-31 level in serum tended to be higher in patients with atopic dermatitis (group B), followed by patients with syringomyelia (group A) and the control group (group C) with the lowest mean IL-31 level (Table 1), but there was only a significant difference between the IL-31 level in the serum samples of patients with atopic dermatitis (group B) and the healthy control group (group C) (p = .0278, Fig. 2).
