Correlations between the levels of GDF11 and systemic inflammatory markers.

Notes: Correlations between the levels of plasma GDF11 and the amounts of IL-6 (A), hs-CRP (B), fibrinogen (C), and MDA (D) were investigated. r is the correlation coefficient. Data were analyzed by the Spearman’s rank test. Closed circles (gray): GOLD stage I/II; closed circles (black): GOLD stage III/IV.
