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

backgroundOral immunotherapy (OIT) induces desensitization in peanut allergy, yet 15%-30% of patients do not respond, and a significant risk of anaphylaxis due to treatment remains. In a placebo-controlled peanut OIT trial, this study identifies molecular drivers of OIT responsiveness through multi-omics profiling in immune cells.

methodsImmunoglobulins, cytokines, transcriptome, and DNA methylome profiles were analyzed in peanut-stimulated and unstimulated peripheral blood mononuclear cells isolated from peanut-allergic children before and after treatment. Multi-omics profiling focused on OIT responsiveness within the active treatment arm. Additional subgroup analyses were performed to further elucidate molecular mechanisms and potential biomarkers.

resultsComplete responders, tolerating 4500 mg of peanut protein, exhibited lower pre-treatment peanut-specific IgE and Th2 cytokine production (IL-4, IL-5) compared to incomplete responders who tolerated ≤ 1000 mg of peanut protein after treatment. Our primary analysis identified 184 differentially expressed genes and 1001 differentially methylated genes, enriched for innate (ILC3) and adaptive (CD8αα subset of CD8

conclusionThis multi-omics approach underscores the importance of gastrointestinal immune mechanisms underlying the variation in peanut oral immunotherapy responses and offers potential biomarkers for improving treatment strategies.
