Description:For this study, serum samples from 40 children between 0 and 17 years old were included. The samples were subjected to molecular diagnosis by RT-PCR and divided into two groups: Dengue (N=25) and healthy controls (N=15). Serum metabolites were extracted following the Glasgow Polyomics protocol. The metabolites were analyzed by ultra-performance liquid chromatography coupled to a mass spectrometer (UPLC-MS), and the resulting data were analyzed by multivariate statistics using partial least squares discriminant analysis (PLS-DA).
