Phenotypic heterogeneity in the human gut microbiome revealed by subspecies-resolution single-cell transcriptomics.
Article in bioRxiv : the preprint server for biology, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Most of our knowledge about bacterial functional roles in microbiomes comes from bulk measurements. Yet microbial communities are complex ecosystems in which functionally distinct bacterial subpopulations with unique transcriptional states emerge across environmental niches and from interactions with other community members. Such heterogeneous transcriptional states are inherently missed by bulk measurements. To address this gap, we developed multispecies microbial split-pool ligation meta-transcriptomics (metaSPLiT), a scalable, instrument-free single-cell RNA sequencing approach for the microbiome. Using metaSPLiT, we profiled healthy human fecal microbiomes and reconstructed 21,598 single cell transcriptomes belonging to 70 unique bacterial species. We found sub-species functional specialization in
