Data is shown as whole numbers and percentages between brackets. Response to treatment was based on improvement in lung function (FVC %pred > 10% or DLCO %pred > 10%) after 6 months of treatment. Age, lung function, and biomarkers are shown as mean ± SD. aAge at time of blood withdrawal. blung function and scadding stage were measured before start of treatment. Scadding stages: 0 = Normal chest radiograph; I = Bilateral hilar lymphadenopathy (BHL); II = BHL with pulmonary infiltrates; III = pulmonary infiltrates without BHL; IV = fibrosis. SFN: Small fiber neuropathy
