Metabolic profiling of umbilical cord blood in macrosomia.
Article in International journal of obesity (2005), 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
BACKGROUND/
objectiveThe term macrosomia is used to describe neonates with a birth weight of 4000 g or more. Macrosomia is a potential risk factor for obesity and metabolic syndromes in postnatal and adult life, yet little is known about its associations with metabolic difference in the early age. We performed metabolic profiling of umbilical cord blood to discover differential metabolites of macrosomia.
methodsWe conducted a case-control study of full-term singletons with normal maternal glucose tolerance [50 cases (macrosomia, birth weight ⩾4000 g); 50 controls (normal weight, birth weight 2500-3999 g)]. Metabolites in umbilical cord blood were detected using an untargeted metabolomic approach based on gas chromatography/mass spectrometry. We performed logistic regression to evaluate the associations between metabolites and macrosomia. We also performed pathway analysis based on KEGG and MBRole.
resultsCompared with controls, the macrosomia cases had a greater male proportion, gestational age, paternal body mass index (BMI) and maternal pre-pregnancy BMI. Forty-two metabolites differed between the cases and controls. After multivariable adjustment, 2-methylfumarate [adjusted odds ratio (AOR)=1.232, 95% confidence interval (CI): 1.102-1.376], uracil (AOR=38.494, 95% CI: 5.635-262.951), elaidic acid (AOR=0.834, 95% CI: 0.761-0.915), ribose (AOR=0.089, 95% CI: 0.021-0.378), lactulose (AOR=0.815, 95% CI: 0.743-0.894) and 4-aminobutyric acid (AOR=0.835, 95% CI: 0.764-0.912) remained significantly associated with macrosomia. Pyrimidine metabolism and pentose and glucuronate interconversions were the two top-ranking pathways enriched with those metabolites (-log P-value=3.49 and 2.47, respectively).
conclusionLevels of 2-methylfumarate, uracil, ribose, elaidic acid, lactulose and 4-aminobutyric acid were associated with the incidence of macrosomia. The alteration of pathways involving those factors might be linked with the incidence of macrosomia and relevant metabolic syndromes later in life, and further studies are needed to confirm it and verify the mechanisms.
