From: Plasma metabolomics for the diagnosis and prognosis of H1N1 influenza pneumonia
Univariate analysis showing important metabolites/features between samples of patients with H1N1 pneumonia and bacterial pneumonia samples. The top ten metabolites detected by proton nuclear magnetic resonance (first line) and gas chromatography-mass spectrometry (second line) that have significantly changed in plasma between samples of patients with H1N1 pneumonia and culture-positive bacterial pneumonia samples (units in normalized and scaled concentrations). The x-axis shows the specific metabolite, and the y-axis is the relative concentration when samples of patients with community-acquired pneumonia are compared with the samples of patients with H1N1. The box-and-whisker plots show the mean and SD of the metabolite
