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

Tryptophan metabolism plays a key role in host-microbiota interactions, producing a wide array of bioactive metabolites. However, our understanding of the interactions between tryptophan metabolites and the gut microbiota is still limited. Using targeted quantitative metabolomics and metagenomics in mice across various compartments, we showed that the cecal microbiota massively impacts tryptophan metabolism both in the gut and systemically. Grouping bacterial taxa in co-abundance guilds better reflected the links between gut microbes and tryptophan metabolites than single taxa taken individually and suggested the involvement of complex microbial interactions in tryptophan metabolism regulation. Finally, analyzing functional data, we shed light on the potential links between tryptophan metabolism and bacterial enzymes or metabolic pathways.
