Postpartum metabolomics profile predicts 8-years postdelivery women's subclinical atherosclerosis measures.
Article in Scientific reports, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
This study evaluates women's metabolomics profiles and subclinical measures of atherosclerosis. Pregnant women (< 20 weeks' gestation) living in Mexico City, Mexico, were recruited in 2007-2011 to the PROGRESS cohort. Serum untargeted metabolomics data at 1-month postpartum were analyzed using chromatography high-resolution mass spectrometry (LC-HRMS), and carotid intima media thickness (CIMT) was measured 8-years postdelivery using B-mode ultrasound. A metabolome-wide association study was conducted to identify metabolites associated with CIMT measures, adjusting for age, education, pre-pregnancy BMI, and smoking exposure. Class-and pathway-based enrichment analysis was performed. Metabolites of the superclasses lipids, organic acids, oxygen compounds, benzenoids and organoheterocyclic compounds were significantly associated with CIMT. The associations included relevant lipid-like metabolites such as 9S- and 13S-HODE, sphinganine-1-phosphate, the branched-chain amino acid 3-Methyl-2-Oxovaleric acid, and the benzenoid phenylpyruvic acid. The related biological pathways included regulation of white adipocyte differentiation, PPARalpha activation of gene expression, and regulation of lipid metabolism. Several metabolites at early postpartum were associated with 8-years postdelivery CIMT. These results highlight the potential of metabolomics as early markers for long-term women´s cardiovascular health.
