Sensitivity and specificity of serum CCL-18 and IL-23 concentrations to distinguish COPD from healthy people. (A) The ROC analysis showed that serum CCL-18 concentrations to distinguish COPD from healthy people had a moderate-high sensitivity and specificity (AUC = 0.870, p < 0.001). (B) To distinguish COPD from healthy people, serum IL-23 concentrations had a considerable sensitivity and specificity (AUC = 0.799, p < 0.001). (C) The sensitivity and specificity of serum CCL-18 and IL-23 to identify COPD did not show significant differences (difference between areas = 0.0393, p = 0.1799). CCL-18, chemokine (C–C Motif) ligand 18; IL-23, interleukin 23; AUC, area under the ROC curve; ROC, receiver operating characteristic curve.
