Fig. 1From: Metabolomics of bronchoalveolar lavage in children with persistent wheezingThe analysis of LC/MS of BAL samples. A Showed the classification and proportion of metabolites. B Showed an OPLS-DS score plot of BAL samples between PW children and control children. C Showed a permutation test plot for OPLS-DA model of BAL samples. D Showed a volcano plot displaying the differential metabolites of PW children relative to control children. BAL bronchoalveolar lavage, PW persistent wheezingBack to article page
