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

Pulmonary function BAFF in serum APRIL in serum

  1. BAFF, B cell-activating factor; APRIL, a proliferation-inducing ligand; 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
