Figure 2.

Receiver-operating characteristic (ROC) analysis. ROC curve depicting sensitivity versus 1-specificity of Aspergillus qPCR assay as a function of detection threshold of fungal burden in the BAL pellet (1 pg = 1000 fg). One genome of A. fumigatus corresponds to about 30-fg of genomic DNA and is estimated to have 28 copies of the target 18S rRNA gene.
