From: The elevation of serum napsin A in idiopathic pulmonary fibrosis, compared with KL-6, surfactant protein-A and surfactant protein-D

Figure 1

Distribution of serum napsin A (A), KL-6 (B), SP-A (C), and SP-D (D) levels in patients with interstitial lung disease (IPF, n = 20), patients with primary pulmonary adenocarcinoma (lung cancer, n = 34), and healthy volunteers (control, n = 20). Each horizontal line represents the diagnostic cut-off level (78.5 ng/ml for napsin A, 555.0 U/ml for KL-6, 42.8 ng/ml for SP-A, and 131.0 ng/ml for SP-D). IPF, idiopathic pulmonary fibrosis; SP-A, surfactant protein A; SP-D, surfactant protein D. **: p < 0.01. n.s.: not significant.
