Comparative genomic analysis of selenium utilization traits in different marine environments.
Article in Journal of microbiology (Seoul, Korea), 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
Selenium (Se) is an essential trace element for many organisms, which is required in the biosynthesis of proteins with selenocysteine, tRNAs with selenouridine, and certain enzymes with Se as a cofactor. Recent large-scale metagenomics projects provide a unique opportunity for studying the global trends of Se utilization in marine environments. Here, we analyzed samples from different marine microbial communities, revealed by the Tara Oceans project, to characterize the Se utilization traits. We found that the selenophosphate synthetase gene, which defines the overall Se utilization, and Se utilization traits are present in all samples. Regions with samples rich and poor in Se utilization traits were categorized. From the analysis of environmental factors, the mesopelagic zone and high temperature (> 15°C) of water are favorable, while geographical location has little influence on Se utilization. All Se utilization traits showed a relatively independent occurrence. The taxonomic classification of Se traits shows that most of the sequences corresponding to Se utilization traits belong to the phylum Proteobacteria. Overall, our study provides useful insights into the general features of Se utilization in ocean samples and may help to understand the evolutionary dynamics of Se utilization in different marine environments.
