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

Malnutrition affects over 30 million children annually and has profound immediate and enduring repercussions. Survivors often suffer lasting neurocognitive consequences that impact academic performance and socioeconomic outcomes. Mechanistic understanding of the emergence of these consequences is poorly understood. Using multi-system SHAP interpreted random forest models and network analysis, we show that Moderate Acute Malnutrition (MAM) associates with enrichment of faecal Rothia mucilaginosa, Streptococcus salivarius and depletion of Bacteroides fragilis in a cohort of one-year-old children in Dhaka, Bangladesh. These microbiome changes form interconnected pathways that involve reduced plasma odd-chain fatty acid levels, decreased gamma and beta electroencephalogram power in temporal and frontal brain regions, and reduced vocalization. These findings support the hypothesis that prolonged colonization by oral commensal species delay gut microbiome and brain development. While causal links require empirical validation, this study provides insights to improve interventions targeting MAM-associated neurodevelopmental deficits.
