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

The Miscellaneous Crenarchaeota group (MCG) Archaea is one of the predominant archaeal groups in anoxic environments and may have significant roles in the global biogeochemical cycles. However, no isolate of MCG has been cultivated or characterized to date. In this study, we investigated the genetic organization, ecophysiological properties and evolutionary relationships of MCG archaea with other archaeal members using metagenome information and the result of gene expression experiments. A comparison of the gene organizations and similarities around the 16S rRNA genes from all available MCG fosmid and cosmid clones revealed no significant synteny among genomic fragments, demonstrating that there are large genetic variations within members of the MCG. Phylogenetic analyses of large-subunit+small-subunit rRNA, concatenated ribosomal protein genes and topoisomerases IB gene (TopoIB) all demonstrate that MCG constituted a sister lineage to the newly proposed archaeal phylum Aigarchaeota and Thaumarchaeota. Genes involved in protocatechuate degradation and chemotaxis were found in a MCG fosmid 75G8 genome fragment, suggesting that this MCG member may have a role in the degradation of aromatic compounds. Moreover, the expression of a putative 4-carboxymuconolactone decarboxylase was observed when the sediment was supplemented with protocatechuate, further supporting the hypothesis that this MCG member degrades aromatic compounds.
