What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundTo compare the impact of two different lipid emulsions, specifically a soybean oil-based emulsion and a multiple oil emulsion (soybean oil, medium-chain triglycerides, olive oil, and fish oil, SMOF), on serum metabolites of very low birth weight (VLBW) infants using untargeted metabolomics analysis.
methodsA comparative study was conducted on 25 VLBW infants hospitalized in neonatal intensive care units (NICU) of Hangzhou Women's Hospital in 2023. The infants were divided into the SMOF group (13 cases) and the soybean oil group (12 cases) based on the type of lipid emulsion used during parenteral nutrition. Serum samples were collected at birth and 14 days later from both groups. An untargeted metabolomics analysis was conducted on serum samples using Ultra-high Performance Liquid Chromatography - Tandem Mass Spectrometry (UHPLC-MS/MS). Differential metabolites were identified using Orthogonal Partial Least Squares Discriminant Analysis (OPLS-DA) modeling, with criteria of variable importance in the projection (VIP) > 1 and false discovery rate (FDR) < 0.05. Functional annotation of the top 30 differential metabolites, ranked by VIP value, was conducted using the Kyoto Encyclopedia of Genes and Genomes (KEGG) database. Subsequently, enrichment and topological analyses were conducted with MetaboAnalyst software to identify key metabolic pathways. Finally, receiver operating characteristic (ROC) analysis was performed on metabolites associated with the identified key metabolic pathways.
resultsThe metabolomic analysis revealed that, in the OPLS-DA model, no significant metabolite differences were found in umbilical cord blood between the two groups. However, 84 differential metabolites were identified in the 14-day samples from the SMOF group compared to the soybean oil group. According to MetaboAnalyst analysis, glycerophospholipid metabolism emerged as the most significantly altered metabolic pathway following the administration of SMOF lipid emulsion. Additionally, ROC curve analysis confirmed a significant increase in LysoPC(20:5), PE(16:0/20:5), and PE-NMe(22:5/16:0) metabolites in the SMOF group.
conclusionThe administration of SMOF lipid emulsion in VLBW infants resulted in significant modifications of serum metabolites compared to traditional soybean oil-based lipid emulsions. Notably, glycerophospholipid metabolism was identified as the most prominently altered metabolic pathway. Metabolites, including LysoPC(20:5), PE(16:0/20:5), and PE-NMe(22:5/16:0), emerged as potential biomarkers. CLINICAL TRIAL NUMBER: Not applicable.
