Cord blood metabolomics data of SGA and AGA infants

This dataset contains the umbilical cord blood metabolomics data generated for the study entitled "Metabolomic analysis of umbilical cord serum in small-for-gestational-age infants with a focus on linear growth", submitted to Scientific Reports. Serum samples were collected from term infants at birth and analyzed using gas chromatography–tandem mass spectrometry (GC-MS/MS). The dataset includes quantified metabolite peak area values for 66 infants, categorized into appropriate-for-gestational-age (AGA), SGA-tall, and SGA-short groups. These data were used for multivariate analyses (orthogonal partial least squares discriminant analysis [OPLS-DA], S-plot, variable importance in projection [VIP] scores), univariate analysis (volcano plots), receiver operating characteristic (ROC) curves, and pathway enrichment analysis. Personal identifiers have been fully anonymized. This dataset supports the findings reported in the associated manuscript.
