From: B cell‐activating factors in autoimmune pulmonary alveolar proteinosis

  BAFF in BALF APRIL in BALF
Pulmonary function ρ p ρ p
VC (% predicted) −0.29 0.04* −0.22 0.14
FVC (% predicted) −0.24 0.07 −0.25 0.10

  1. BAFF, B cell-activating factor; APRIL, a proliferation-inducing ligand; BALF, bronchoalveolar lavage fluid; VC, vital capacity; FVC, forced expiratory volume; FEV1, forced expiratory volume in 1 s; DLco, diffusion capacity for carbon monoxide. Data were analyzed using Spearman’s correlation coefficient. *Significant at the 0.05 level
