Strain transmission links human microbiomes along the oral-gut axis and across cohabiting individuals.
Article in Cell press blue, 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
Interpersonal strain transmission shapes the human microbiome, yet a comparative understanding of the transmission dynamics across body sites is lacking. We analyzed 1,644 paired oral and fecal metagenomes to investigate microbiome transmission among healthy cohabitants and intra-individual oral-gut overlap. Cohabitants shared significantly more oral and gut strains than non-cohabitants. Romantic partners exhibited the highest oral strain-sharing rates, exceeding their gut strain sharing. Higher oral transmissibility was associated with increased longitudinal strain replacement, while the most transmissible gut species were linked to poorer cardiometabolic health. Within individuals, 74.5% of cases of species detected in both sites involved the same strains, primarily related to abundant oral species such as
