Predictive significance of baseline SP-D and CCL18 for longterm changes in FVC in patients not treated with immunosuppressive agents.

Pneumoproteins	p_univariate	b (95% CI)	p_multivariate^*
SP-D	0.742	0.08 (−0.39, 0.54)	0.928
CCL18	0.921	0.06 (−1.19, 1.31)	0.628
SP-D and CCL18	0.769	−0.42 (−1.9, 1.06)	0.571

↵* Adjusted for age, sex, ethnicity, and body mass index. SP-D: surfactant protein D; CCL18: CC-chemokine ligand 18; FVC: forced vital capacity.
