Fig. 4From: Metabolomics profile in acute respiratory distress syndrome by nuclear magnetic resonance spectroscopy in patients with community-acquired pneumoniaReceiver operating characteristic (ROC) curves and areas under the ROC curve (AUCs) before and after treatment in the community-acquired pneumonia with acquired respiratory distress syndrome group. A Combined ROC curve plot based on metabolites screened by VIP selected from serum metabolites. B ROC curve and AUC of the 1-methylnicotinamide screened based on VIP selected from urine metabolites. C ROC curve and AUC based on a total of associated serum and urine metabolites screened by the selected VIP. 3-HB 3-hydroxybutyrate, Acn acetone, Aca acetoacetate, Cit citrate, Cho choline, 1-Mnim 1-methylnicotinamideBack to article page
