Fig. 5From: An integrated metabo-lipidomics profile of induced sputum for the identification of novel biomarkers in the differential diagnosis of asthma and COPDRoc curve analysis of statistically significant compounds. A–D ROC curves were constructed for compounds that exhibited the most effective diagnostic performance and a good ability to distinguish between these two groups, as measured by an Area under the Curve (AUC) around 0.8. ROC curves were acquired by Metaboanalyst softwareBack to article page
