Correlation between plasma BAMBI levels and clinicopathological parameters of patients with COPD.
Correlation of (a) FEV1% predicted value, (b) neutrophil percentage in peripheral white blood cells, (c) plasma TGF-β1 levels and (d) Th17/Treg ratio with plasma BAMBI levels in COPD patients (n = 29). Each symbol represents one individual COPD patient (black dots); a value of P < 0.05 was considered statistically significant.
