IL13 and neoplasm: Non-parametric correlation (Spearman) analysis between chemokine (C–C motif) ligand (CCL)-3 and CCL-4 with the protein expression of the cytokine anti-inflammatory cytokine IL-13 in the tumor of cachectic patients was found to be significant (p = 0.0089); while the relationship between CCL4 and IL-13 (p = 0.147) was not (Figures 6D,H).
