Expansion of the genomic and functional diversity of global ocean giant viruses.
Article in Npj viruses, 2025. 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
Giant viruses (GVs) play crucial roles in the global ocean microbial food web and biogeochemistry. Recent metagenomic advances have uncovered >1800 new GV genomes from the world's oceans. While this rapid increase in genomic information is impressive, it is nowhere close to the extensive genomic information available for other marine entities-e.g., prokaryotes and their "virome". We present 230 new high-quality GV genomes (genomes with 4 or more marker genes) and 398 partial genomes from nine global ocean datasets. Notably, we identified numerous GV genomes from the Baltic Sea, offering insights into their phylogenomics, metabolic potential, and environmental drivers in one of the largest brackish water ecosystems. We discovered new GV functions and identified a significant functional divide between the Imitervirales and Algavirales orders. Additionally, we evaluated factors affecting GV abundance through a case study on the Baltic Sea dataset. Our study significantly expands the marine GV genomic and functional diversity, broadening our understanding of their roles in the food web and biogeochemistry.
