Functional bias of positively selected genes in Streptococcus genomes.

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
Rates of nonsynonymous substitution (dN) significantly higher than rates of synonymous substitution (dS) have been used as evidence of positive selection for the fixation of advantageous point mutations. It has been suggested that positive selection contributes to the evolution of virulence factors and certain functional categories in bacterial pathogens. The genus Streptococcus contains a number of important human and agricultural pathogens. Here we assessed positive selection across 13 Streptococcus species, and their relationship with virulence factors and functional categories. We found that known virulence genes were subject to positive selection pressure as much as other genes. After false discovery rate correction for multiple comparisons, no functional categories were significantly over- or under-represented in positively selected genes relative to other genes. Our results suggest that within the genus Streptococcus positive selection based on dN/dS ratios is not distributed with bias across biological functions.
