Serum suPAR and FEV1 % of predicted in patients with acute exacerbation of chronic obstructive pulmonary disease.
Notes: Serum suPAR was correlated inversely with FEV1% of predicted using Pearson correlation (r=−478, P=0.001).
Abbreviations: FEV1, forced expiratory volume in 1 second; ln, natural log-transformed; suPAR, soluble urokinase-type plasminogen activator receptor.
