1 · What the graph read from it

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.

2 · The registry

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

backgroundGestational diabetes mellitus (GDM) affects the transfer of fatty acid (FA) from mother to fetus. However, the specific transport alterations remain unclear. This study investigated FA transport from mother to fetus in GDM.

methodsMaternal serum, umbilical cord serum, and placental tissues were collected from 20 healthy (normal group) and 20 GDM pregnancies receiving glycemic management (GDM group). Fifty-one FA were quantified by gas chromatography-mass spectrometry. Placenta/mother and fetus/placenta ratios of FA compositions were compared between groups using Student's t-test or Mann-Whitney U test, as appropriate.

resultsThe concentrations and compositions of FA profiles were both changed in GDM. The placenta/mother ratios of cis-11,14,17-eicosatrienoic acid (GDM vs normal: 0.648 vs 0.484,

conclusionsFA profiles in mother, placenta, and fetus were affected by GDM despite glycemic management, especially in omega-3 and omega-6 LC PUFAs. This finding indicates that addressing fetal FA deficiency may depend on correcting placental dysfunction rather than solely increasing maternal FA supplementation, offering insights for developing nutritional and therapeutic strategies for GDM.
