Genetic Diversity and Potential of Cyanobacteria and Fungi Living on Arctic Liverworts.
Article in Microbial ecology, 2025. 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
Liverworts often form symbiotic associations with fungi and cyanobacteria, yet the distribution and specificity of these relationships remain largely unexplored, particularly in Arctic environments. This study used metagenomic sequencing to investigate fungal and cyanobacterial communities associated with Arctic liverworts, analyzing photosynthetic parts of gametophytes and their rhizoids with attached soil separately. The results revealed that Ascomycota dominated the fungal community. The cyanobacterial community was primarily composed of heterocytous Nostoc and non-heterocytous filamentous Leptolyngbya, with Nostoc showing evidence of nitrogen fixation, especially in gametophytes, suggesting a potential role in enhancing nitrogen availability for the host. These findings underscore the ecological significance of liverwort-associated microorganisms in Arctic ecosystems, with microbial composition differing between upper and lower parts of plants, as well as between leafy and thalloid liverworts, indicating possible functional specialization.
