Figure 3

Correlations between OPN and clinical variables. (a, b, e) No correlations were noted between OPN and FVC% predicted, DLCO% predicted, and KL-6. (r = −0.153, ; r = −0.272, ; and r = 0.216, ). (c, d) Spearman correlations showed weak, yet significant correlations between OPN and inflammatory factors including CRP (r = 0.477, ) and LDH (r = 0.264, ).
