Adaption mechanism and ecological role of CPR bacteria in brackish-saline groundwater.
Article in NPJ biofilms and microbiomes, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Candidate phyla radiation (CPR) constitutes a substantial fraction of bacterial diversity, yet their survival strategies and biogeochemical roles in brackish-saline groundwater remain unknown. By reconstructing 399 CPR metagenome-assembled genomes (MAGs) and 2007 non-CPR MAGs, we found that CPR, affiliated with 44 previously proposed phyla and 8 putative novel phyla, played crucial roles in maintaining the microbial stability and complexity in groundwater. Metabolic reconstructions revealed that CPR participated in diverse processes, including carbon, nitrogen, and sulfur cycles. Adaption of CPR to high-salinity conditions could be attributed to abundant genes associated with heat shock proteins, osmoprotectants, and sulfur reduction, as well as their cooperation with Co-CPR (non-CPR bacteria co-occurred with CPR) for metabolic support and resource exchange. Our study enhanced the understanding of CPR biodiversity in high-salinity groundwater, highlighting the collaborative roles of self-adaptive CPR bacteria and their reciprocal partners in coping with salinity stress, maintaining ecological stability, and mediating biogeochemical cycling.
