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

Pan-genome refers to the sum of genes that can be found in a given bacterial species, including the core-genome and the dispensable genome. In this study, the genomes from 183 Streptococcus mutans (S. mutans) isolates were analyzed from the pan-genome perspective. This analysis revealed that S. mutans has an "open" pan-genome, implying that there are plenty of new genes to be found as more genomes are sequenced. Additionally, S. mutans has a limited core-genome, which is composed of genes related to vital activities within the bacterium, such as metabolism and hereditary information storage or processing, occupying 35.6 and 26.6% of the core genes, respectively. We estimate the theoretical core-genome size to be about 1083 genes, which are fewer than other Streptococcus species. In addition, core genes suffer larger selection pressures in comparison to those that are less widely distributed. Not surprisingly, the distribution of putative virulence genes in S. mutans strains does not correlate with caries status, indicating that other factors are also responsible for cariogenesis. These results contribute to a more understanding of the evolutionary characteristics and dynamic changes within the genome components of the species. This also helps to form a new theoretical foundation for preventing dental caries. Furthermore, this study sets an example for analyzing large genomic datasets of pathogens from the pan-genome perspective.
