Microbial metabolite oxindole curbs acute lung injury by suppressing CXCL13.

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.
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
The gut-lung axis is involved in acute lung injury (ALI) and its fatal sequela, acute respiratory distress syndrome (ARDS), yet the molecular mechanisms governing this crosstalk remain poorly defined. Untargeted metabolomics of plasma revealed significant dysregulation of tryptophan metabolism in ARDS patients compared to healthy controls. Murine dietary interventions demonstrated that high tryptophan intake alleviated ALI severity, whereas deficiency exacerbated injury, with protection being gut microbiota dependent. 16S ribosomal RNA (16S rRNA) gene sequencing revealed marked depletion of a functionally central bacterium
