The social microbiome: The missing mechanism mediating the sociality-fitness nexus?
Review in iScience, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
In many social mammals, early social life and social integration in adulthood largely predict individual health, lifespan, and reproductive success. So far, research has mainly focused on chronic stress as the physiological mediator between social environment and fitness. Here, we propose an alternative, non-exclusive mechanism relying on microbially mediated effects: social relationships with conspecifics in early life and adulthood might strongly contribute to diversifying host microbiomes and to the transmission of beneficial microbes. In turn, more diverse and valuable microbiomes would promote pathogen resistance and optimal health and translate into lifelong fitness benefits. This mechanism relies on recent findings showing that microbiomes are largely transmitted via social routes and play a pervasive role in host development, physiology and susceptibility to pathogens. We suggest that the social transmission of microbes could explain the sociality-fitness nexus to a similar or higher extent than chronic social stress and deserves empirical studies in social mammals.
