Fig. 3From: Serum (1→3)-β-D-glucan and galactomannan levels in patients with cystic fibrosis: a retrospective cohort studyReceiver-operating-characteristic (ROC)-analysis for discrimination between A. fumigatus-positive and -negative patients. The cut-off with the highest Youden index (black circles) was ≥60 pg/ml for BDG (sensitivity 50.0%, specificity 80.5%) and > 0.1 ODI for GM (sensitivity 45.5%, specificity 78.0%). The area under the ROC-curve was not significantly different for BDG and GM (0.658 versus 0.635, p = 0.760). BDG: (1→3)-β-D-glucan; GM: galactomannanBack to article page
