Figure 3. — Dlco correlations with GDF-15. A, There is a significant negative correlation between plasma levels of GDF-15 and Dlco (% predicted value, corrected for alveolar volume) in subjects with SSc (Spearman r = −0.6510, P < .0001, n = 38). B, The FVC to Dlco ratio has a significant positive correlation with plasma GDF-15 levels in subjects with SSc (Spearman r = 0.5967, P < .0001, n = 40). Dlco = diffusing capacity of the lung for carbon monoxide. See Figure 1 and 2 legends for expansion of other abbreviations.
