Correlations between the levels of GDF11 and lung function data.

Notes: Correlations between the levels of plasma GDF11 and the values of FEV₁ % predicted (A), FVC % predicted (B), IC (C), and D_Lco’ % predicted (D) were investigated. Data were statistically analyzed by the Spearman’s rank test. Closed circles (gray): GOLD stage I/II; closed circles (black): GOLD stage III/IV.

Abbreviations: D_Lco’, diffusing capacity of the lung for carbon monoxide; FEV₁, forced expiratory volume in 1 second; FVC, forced vital capacity; GDF11, growth differentiation factor 11; GOLD, Global Initiative for Chronic Obstructive Lung Disease; IC, inspiratory capacity.
