ROC curves of Aspergillus IgG antibody in different groups. a: The ROC curve of Aspergillus IgG antibody in the pulmonary aspergillosis group compared with the healthy group; the cut-off value (sensitivity, specificity) = 71.555 (0.793, 0.677) and AUC = 0.780, P < 0.001. b: The ROC curve of Aspergillus IgG antibody in the IPA group compared with the CPA group; the cut-off value (sensitivity, specificity) = 77.310 (0.405, 0.952) and AUC = 0.624, P < 0.001. c: The ROC curve of Aspergillus IgG antibody in the IPA group compared with the community-acquired bacterial pneumonia and healthy groups; the cut-off value (sensitivity, specificity) = 134.460 (0.459, 0.923) and AUC = 0.727, P < 0.001. d: The ROC curve of Aspergillus IgG antibody in the CPA group compared with the community-acquired bacterial pneumonia and healthy groups; the cut-off value (sensitivity, specificity) = 75.460 (0.952, 0.692) and AUC = 0.873, P < 0.001. e: The ROC curve of Aspergillus IgG antibody in the IPA group compared with the CPA, community-acquired bacterial pneumonia and healthy groups; the cut-off value (sensitivity, specificity) = 155.640 (0.378, 0.872) and AUC = 0.641, P = 0.013. f: The ROC curve of Aspergillus IgG antibody in the CPA group compared with the IPA, community-acquired bacterial pneumonia and healthy groups; the cut-off value (sensitivity, specificity) = 77.310 (0.952, 0.588) and AUC = 0.782, P < 0.001
