Pre-lavage and post-lavage pulmonary parameters for patients with idiopathic PAP

^*Mean±SD (standard deviation); ^†P value is from the Wilcoxon signed rank test for comparison of pre-lavage versus post-lavage data for each parameter from each patient for whom data were available.

PaO₂, partial pressure of oxygen in arterial blood; D(A-a)O₂, alveolar-arterial O₂ gradient; FEV₁, forced expiratory volume in one second; FVC, forced vital capacity; TLC, total lung capacity; DL_CO, diffusing capacity of the lung for carbon monoxide.
