Phylogenomic analyses indicate the archaeal superphylum DPANN originated from free-living euryarchaeal-like ancestors.

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
The episymbiotic DPANN archaea are thought to be one of the four major archaeal clades. However, the monophyly and placement of DPANN within the archaeal tree remain debated, and their fast-evolving reduced genomes render phylogenetic reconstructions challenging. Here we used 126 highly conserved protein markers, extensive taxon sampling representing the 11 known DPANN phyla and in-depth phylogenomic analyses to reassess DPANN monophyly and their relationships to other archaea. Our analyses robustly support the monophyly and placement within Euryarchaeota, and we identify the probably free-living Altiarchaeota as the earliest diverging DPANN branch. Our phylogenies suggest DPANN probably acquired several hallmark proteins through ancient horizontal gene transfer events from different bacterial donors, notably Patescibacteria and Omnitrophota, two bacterial phyla that also exhibit episymbiotic lifestyles. Overall, the monophyletic DPANN archaea probably evolved from a free-living, euryarchaeal-like ancestor, with proteins of bacterial origin playing a role in the emergence of their episymbiotic lifestyle.
