Gut-placenta axis: gut microbiota metabolites may play a role in regulating maternal-fetal immune tolerance and the pathogenesis of adverse pregnancy outcomes.
Review in Frontiers in immunology, 2026. 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
Pregnancy is a unique physiological stage characterized by the coordinated remodeling of maternal metabolism, immunity, and endocrine systems. Previous studies have primarily focused on the local uterine microenvironment, neglecting the role of the maternal gut microbiota in mediating distal, cross-organ regulation via the gut-placental axis. The concept of the gut-placental axis was formally proposed in 2018 and has attracted widespread research attention in recent years. Studies using germ-free animals, fecal microbiota transplantation (FMT), and
