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
introductionMaternal fish oil (FO) supplementation during pregnancy has been shown to improve pregnancy outcomes. FO is recognized as dietary source for n-3 polyunsaturated fatty acids (n-3 PUFAs). While early research has focused on the benefits of n-3 PUFAs for fetal neurodevelopment, retinal maturation and neonatal behavior, their roles in the placenta during late pregnancy and in the mammary gland during lactation still remain unknow.
objectivesHere, we aim to clarify the mechanisms by which maternal supplementation with FO during pregnancy and lactation affects placental and mammary gland function.
methodsWe evaluated the effects of FO on maternal placental nutrient transport, mammary gland milk synthesis and offspring growth. We then explored the molecular mechanisms by which docosahexaenoic acid (DHA) affects the biological function of placental trophoblast cells and mammary epithelial cells through in vitro experiments. Finally, a lipopolysaccharide-challenged experiment was performed to access the potential of maternal FO supplementation in alleviating offspring intestinal inflammation.
resultsMaternal supplementation with FO during late pregnancy increased offspring birth weight, associated with enhanced maternal placental vascularization and nutrient transporter abundance. Additionally, maternal FO supplementation during lactation improved milk biosynthesis, increasing the fat, protein, and non-fat solids content in both colostrum and mature milk, thereby promoting offspring growth. The stimulatory effects of DHA on nutrient transportation in placental trophoblast cells and nutrient secretion in mammary gland epithelial cells were mediated by GPR120 signaling pathways. Furthermore, maternal FO supplementation strengthened the placental barrier, reduced placental inflammation, oxidative stress and alleviated lipopolysaccharide-induced intestinal inflammation in offspring.
conclusionMaternal FO supplementation during late pregnancy and lactation enhances offspring growth by increasing placental nutrient transport and milk biosynthesis, mediated by GPR120. Additionally, maternal FO supplementation reduces the susceptibility of offspring to intestinal inflammation.
