The brain-gut axis in autism spectrum disorder: from gastrointestinal dysfunction to neuroimmune mechanisms.
Review in Frontiers in psychiatry, 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
Autism spectrum disorder (ASD) is a neurodevelopmental condition characterized by social deficits and repetitive behaviors, often accompanied by gastrointestinal (GI) symptoms such as constipation, diarrhea, and abdominal pain. Emerging evidence highlights the gut-brain axis as a key pathway linking GI dysfunction to ASD pathophysiology. This review synthesizes current findings on the interplay among dietary patterns, gut microbiota dysbiosis, intestinal barrier dysfunction, and neuroimmune activation in ASD. We also discuss shared genetic vulnerabilities and environmental factors influencing both gut and brain function. Finally, we evaluate microbiota-targeted interventions, including probiotics and fecal microbiota transplantation, as potential therapeutic strategies. Understanding these mechanisms may inform personalized approaches to managing GI and behavioral symptoms in ASD.
