Figure 1

Changes of serum CCL-18 and IL-23 concentrations in COPD patients. (A) Patients with stable COPD showed higher serum CCL-18 concentrations compared with control group (p < 0.001). (B) The serum CCL-18 concentrations in AECOPD patients were higher than that in stable COPD patients (p < 0.001). (C) Patients with stable COPD showed high concentrations of serum IL-23 compared with control group (p < 0.001). (D) The serum IL-23 concentrations in AECOPD patients were higher than that in stable COPD patients (p = 0.001). COPD, chronic obstructive pulmonary disease; CCL-18, chemokine (C–C Motif) ligand 18; IL-23, interleukin 23; M ± SD, mean ± standard deviation.
