Fig. 1From: Clinical significance of serum anti-granulocyte–macrophage colony-stimulating factor autoantibodies in patients with sarcoidosis and hypersensitivity pneumonitisThe ROC curve to discriminate aPAP from healthy controls. The best cut-off value of GMAb for discriminating aPAP (n = 110) from healthy controls (n = 31) was 3.33 μg/mL (AUC = 1.000, p < 0.0001, sensitivity 100%, specificity 100%). The cut-off value was determined by Youden's index. aPAP autoimmune pulmonary alveolar proteinosis, GMAb anti-granulocyte–macrophage colony-stimulating factor autoantibodyBack to article page
