Cohesive modules of engraftment in fecal microbiota transplantation.
Article in iScience, 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
While single-strain probiotics fail to address community-level microbiota injuries in dysbiosis-related conditions and fecal microbiota transplantation (FMT) produces unpredictable communities, a middle-ground approach has emerged. This approach involves using small consortia of species, combining the precision of single-strain probiotics and the holistic approach intrinsic to FMT. The species selection in this oligomicrobial strategy is typically proprietary or based on studies linking single species to disease or health. To advance this approach, we developed the concept of cohesive modules of engraftment (CME) and a workflow for their identification from FMT trials. CMEs represent small donor microbiota subsets that engraft as units (modularity), while maintaining their original composition (cohesiveness). In benchmarking, we identified >200 highly cohesive CMEs (2-5 species) in 5 FMT trials and found evidence for cross feeding as a mechanism for CME integrity. Due to their predictable post-treatment compositions, CMEs deserve investigation as potential ingredients of future therapeutic microbial consortia.
