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

Background: Neurodevelopmental disorders (NDDs) have been linked to changes in the gut microbiome, but the exact nature of these alterations is not fully understood. This research seeks to explore the variations in both the diversity and composition of the gut microbiota in individuals diagnosed with NDDs. Methods: We conducted a systematic literature search up to April 2025. Meta-analyses using STATA 16.0 evaluated alpha diversity, beta diversity, and relative abundance between individuals with NDDs and healthy controls. Results: No significant alpha diversity differences were found between NDD and control groups. Beta diversity analysis revealed distinct microbial communities across autism spectrum disorder (ASD), attention-deficit/hyperactivity disorder (ADHD), and tic disorder (TD) subgroups. At the family level, NDDs showed increased Peptostreptococcaceae (SMD = 0.47; 95% CI: 0.05 to 0.90). Genus-level analysis demonstrated reduced Conclusion: This study highlights the complex changes in gut microbiota in NDDs, particularly significant differences at the beta diversity, family, and genus levels. However, the results are constrained by research heterogeneity and small sample sizes. To better elucidate these associations, larger, more standardized studies are required.
