Relationship between the serum level of IL-19 and pulmonary function in patients with stable COPD.

Notes: (A) The scatter point plot for IL-19 and FEV₁/FVC indicated that the two variables belonged to normal distribution (P>0.05). (B) The dependent variable is approximately linear with the standardized predictive value, indicating that serum IL-19 and FEV₁/FVC of patients had a linear correlation (P<0.05). (C) The scatter point plot for IL-19 and FEV₁% predicted indicated that the two variables belonged to normal distribution (P>0.05). (D) The dependent variable is approximately linear with the standardized predictive value, indicating that serum IL-19 and FEV₁% predicted that patients had a linear correlation (P<0.05).

Abbreviation: cum prob, cumulative probability.
