Significant positive correlations with the diagnosis of allergic contact dermatitis were found for TNF-α (r = 0.290, P < 0.01), MCP-1 (r = 0.312, P < 0.01), TPX (r = 0.769, P < 0.0001), and OSI (r = 0.769, P < 0.0001), and negative correlations for IL-10 (r = −0.255, P < 0.05), and TAC (r = −0.485, P < 0.0001). Here, CCL2 is linked to allergic contact dermatitis.
