Relationship between the clinical parameters and serum level of IL-19 in serum of stable COPD patients.

Notes: (A) ^⋆Patients with stable COPD showed a higher expression of serum IL-19 compared with the control group (P<0.001). (B) Serum IL-19 expression did correlate with the patient’s age (P=0.841). (C) Serum IL-19 expression did correlate with the patient’s smoking status (P=0.110). (D) ^⋆⋆Serum IL-19 level of patients with GOLD 3 and 4 of COPD was increased compared with those of GOLD 1 and 2 (P=0.004). (E) ^♦The patients with mMRC scores of 3 and 4 showed a higher serum level of IL-19 compared with those with mMRC score of 2 (P<0.001). (F) ^♦♦Serum IL-19 in patients with longer medical history was increased compared to those with short history (P=0.002).
