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

Trace amine-associated receptors (TAARs) are a class of G protein-coupled receptors with roles in olfaction, behaviour, and immunity. Known best as an olfactory receptor, TAAR5 has been linked to emotional behaviour and hippocampal neurogenesis, yet its peripheral mechanisms remain poorly understood. Given bidirectional influences between the gut microbiota and the host, we investigated whether TAAR5 deletion alters the gut microbiome in mice. Using 16S rRNA sequencing, we compared the gut microbiota of TAAR5-knockout (TAAR5-KO) and wild-type mice. While alpha-diversity remained unchanged, beta-diversity analysis revealed significant separation between genotypes, with TAAR5-KO mice exhibiting markedly increased inter-individual variability. Taxonomically, KO mice showed a significant reduction in
