From: Multi-level immune response network in mild-moderate Chronic Obstructive Pulmonary Disease (COPD)
Multilevel (lung and blood) Spearman correlation network (|r| > 0.3, p < 0.05) for all participants (n = 65) of lung (green), peripheral blood (red) immune cell populations, lung function variables (blue) and general systemic inflamatory biomarkers (yellow). Positive correlations are represented with a continuous edge while the negatives are with a discontinuous edge. Edge witdth is proportional to the strength of the correlation. Node size is proportional to the mean percentatge of CD45% cells of the population. Blue links are used to highlight correlations between lung and blood markers. For further explanations, see text
