Correlation between candidate biomarkers and immune-infiltrated cells. (a) Box plot displayed the immune cell infiltration levels between COPD samples and normal samples. (b) Bubble plots showed the correlation between candidate biomarkers and immune-infiltrated cells. (c) Heatmap exhibited the correlation between candidate biomarkers and the marker genes of B cells.
