1 · What the graph read from it

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.

2 · The registry

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

Genome remodeling and exchange of sequences are widespread in the prokaryotic world and mosaic genomes challenge the classification of prokaryotes, which cannot be properly achieved in terms of a single gene or group of genes. Here, we studied individually the gene collection of the archaic microorganism Lokiarchaeum sp., suggested as an archaeal host close to the emergence of the eukaryotes. The network or rhizome of all Lokiarchaeum sp. genes revealed that the genomic repertoire is mainly composed of genes from archaeal (∼36%) and bacterial origin (∼28%), distantly followed by components of eukaryotic origin (∼2%). Thirty-three percent of genes were unique to this species (ORFans). The mosaicity of archaea was also supported by studying Methanomassiliicoccus luminyensis, an archaea from the gut, in which 67% of the genomic repertoire arised from archaea and 22% from bacteria. Our results illustrate the intricate evolutionary relationships of the archaeal genome repertoire and highlight the rhizome-like processes of evolution in archaea, their mosaicity, and chimeric origin composed of different domains of life, questioning the reality of a tree of life.
