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

Autism spectrum disorder (ASD) is a complex neurodevelopmental condition characterized by behavioral, cognitive, and motor impairments. There is increasing evidence linking ASD with an altered composition of the gut microbiota and chronic low-grade inflammation, suggesting a key role of the gut-brain axis (GBA) in the pathophysiological development of this condition. This mini review explores the molecular and immunological mechanisms underlying the associations between ASD and gut dysbiosis, with particular emphasis on the therapeutic potential of fecal microbiota transplantation (FMT). Dysbiosis can compromise the integrity of the intestinal barrier, increasing permeability and the translocation of pathogen-associated molecular patterns (PAMPs), such as lipopolysaccharides (LPS), thereby releasing inflammatory cytokines, including IL-6 and TNF-α. These mediators activate the mucosal immune pathways, such as the NF-κB signaling and NLRP3 inflammasome, thereby contributing to neuroinflammation and elevating intestinal biomarker levels, such as S100B, RANTES, and calprotectin. Emerging evidence suggests that FMT may restore microbial diversity, promote the expansion of beneficial short-chain-fatty-acid-producing taxa, and reinforce intestinal tight junction proteins, thereby improving the integrity of the gut barrier. These effects may attenuate systemic inflammation, modulate central immune responses, regulate neurotransmitter levels, and improve gastrointestinal and behavioral outcomes in individuals with ASD. Despite these promising findings, current evidence remains limited by small sample sizes, methodological heterogeneity, and short follow-up periods. Hence, future research efforts should prioritize well-designed randomized controlled trials and the development of personalized microbial-based interventions to establish FMT as a safe and effective therapeutic strategy for ASD.
