Correlation between circulating arterial cytokines and airway obstruction for AATD COPD patients (i.e. AATD + AUG and AATD-AUG groups shown as shaded circles) and for non-AATD COPD patients (open triangles). Dotted regression line reflect data for AATD COPD, whereas dashed regression line reflect data for non-AATD COPD.
