Metabolomics and glucose tolerance in pregnancy and postpartum: The PONCH study.
Article in PloS one, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
aimsPregnancy induces significant physiological changes, particularly important in obesity (OB) and gestational diabetes (GDM). We aimed to determine metabolite changes and their relation to clinical variables of obesity and glucose metabolism.
methodsSerum NMR metabolomics, clinical data, and body composition were determined in normoglycemic normal-weight (NW) (n = 32) and OB (n = 33) women at six time points spanning pregnancy and postpartum. Additionally, 31 GDM women (15 GDM-NW and 16 GDM-OB) were assessed during trimester 3.
resultsProfound shifts in the metabolome during pregnancy were exemplified by decreased branched chain amino acids (BCAAs) and tyrosine, and increased phenylalanine, succinate, lactate, and pyruvate. Comparison with clinical variables showed strong correlation between BCAAs' and bodyfat and insulin resistance mainly in the non-pregnant state. Conversely, pyruvate and lactate exhibited robust correlations with bodyfat, insulin resistance, and adipokines during pregnancy. Comparisons in late pregnancy showed higher levels of BCAAs, phenylalanine, lactate, and pyruvate in both obesity and GDM (GDM-NW and GDM-OB).
conclusionsBCAAs are elevated in obesity and GDM although may not be directly related to pregnancy-induced insulin resistance. Conversely, pyruvate and lactate appear connected to gestational changes of glucose metabolism where underlying obesity may contribute.
