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

T cells, a cornerstone of the adaptive immune system, have pivotal roles at the host-microorganism interface. The gut microbiome profoundly influences T cell biology by producing a diverse repertoire of small molecules that are sensed by host cells. These microbial metabolites regulate all aspects of the T cell lifecycle, from cell development to differentiation and activation to exhaustion. Recent studies have uncovered microbially derived molecules, including short-chain fatty acids, secondary bile acids and tryptophan metabolites, as potent regulators of T cell function. However, the full scope of microbial metabolite-T cell interactions remains largely unexplored. This Review presents a mechanistic framework linking gut microbial metabolites to discrete stages of T cell fate and function. Expanding our understanding of these intricate host-microbiome interactions will reveal new aspects of immune regulation and inspire microbiome-guided therapeutic strategies for infections, autoimmune diseases and cancer immunotherapy.
