Relationship between biomarker levels and pulmonary function parameters. A and B, Relationship between levels of IP-10 or MMP-7 and pulmonary function parameters (forced vital capacity [FVC] and diffusing capacity for carbon monoxide [DLCO] [both measured as the percent predicted]) in the Chinese identification cohort (A) and the US replication cohort (B). C, Relationship between mean serum levels of IP-10 or MMP-7 and the dyspnea score in the US cohort. For all analyses, Spearman’s rank correlation coefficients (rho values) indicate the relative magnitude and direction of covariation between biomarker levels and pulmonary function parameters or dyspnea score. * = P < 0.05. See Figure 1 for other definitions.
