Effects of resveratrol on inflammatory and hormonal disorders induced by Helicobacter pylori OMVs in pregnant mice.
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
Helicobacter pylori (H. pylori) is a type of pathogenic bacteria that can live in the host's stomach for a long time. H. pylori infection affects 50% of the world's population. Outer membrane vesicles (OMVs) secreted by H. pylori can enter the host blood circulation and participate in mediating systemic diseases. However, the effects of OMVs exposure during pregnancy on the inflammatory response and hormone metabolism remain unclear. H. pylori was cultured and its outer membrane vesicles were isolated. The structure and morphology of OMVs were observed by transmission electron microscopy and characterized by LC-MS. E18-19 pregnant mice were injected with OMVs via the tail vein to establish the exposure model and IL-6, IL-1β, TNF-α in the serum of pregnant mice after intragastric administration of Resveratrol (Res) were determined. Targeted metabolomics was used to detect the metabolic changes of related hormones in vivo after Res intervention. In vivo injection of Res can significantly reduce the serum level of IL-6, IL-1β and TNF-α attributable to H. pylori OMVs, improve the imbalance of androgens and steroids caused by H. pylori OMVs and regulate the level of estrogen. Res can inhibit the systemic inflammatory response caused by H. pylori OMVs and regulate the imbalance of androgen and steroid hormones caused by H. pylori OMVs.
