Fig. 1From: Post-acquisition filtering of salt cluster artefacts for LC-MS based human metabolomic studiesRetention time and m/z of plasma metabolites differing significantly between children with severe acute malnutrition and controls (Wilcoxon test, FDR corrected P < 0.1, >2 fold change). Salt clusters are shown in red, with validated metabolites colored according to their charge state. Data was acquired by positive ESIBack to article page
