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

Patients with First-Episode Psychosis (FEP) exhibit variable responses to antipsychotic treatment. Emerging evidence suggests that disease-related dysbiosis of gut and oropharyngeal microbiota may lead to the abnormal translocation of microorganisms via the bloodstream. This study aims to explore the blood microbiome to identify candidate biomarkers associated with treatment outcomes in FEP. To address this, blood samples were collected from twenty drug-naïve individuals with FEP, both before and after four weeks of antipsychotic medication. DNA extracted from these samples underwent 16S rRNA gene sequencing and comprehensive bioinformatics analysis. Clinical assessments were based on the Positive and Negative Syndrome Scale and standard remission criteria. Peripheral cytokines (IL1β, TNF-α, IL10) were quantified by immunoassays. Baseline comparisons showed a significantly greater microbiome alpha diversity in remitters, along with differential prevalence in five taxa and 217 metabolic pathways. Post-treatment assessments uncovered a significantly distinct impact of antipsychotics on blood bacterial composition between remission groups, while initial differences on metabolic profiles persisted. Additionally, strong correlations were observed, linking specific taxa abundances to cytokine levels. Conclusively, this pilot study suggests that blood microbiome profiling could provide novel biomarkers for predicting therapeutic response in early psychosis, paving the way for precision medicine interventions.
