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

In this study, the factors driving genome-wide patterns of codon usages in Lawsonia intracellularis genome are determined. For genes on the chromosome of the bacterium, it is found that the most important source of variation results from strand-specific mutational biases. A lesser trend of variation is attributable to genes that are presumed as horizontally transferred. These putative alien genes are unusually GC richer than the other genes, whereas horizontally transferred genes have been observed to be AT rich in bacteria with medium and relatively low G + C contents. Hydropathy of encoded protein and expression level are also found to influence codon usage. Therefore, codon usage in L. intracellularis chromosome is the result of a complex balance among the different mutational and selectional factors. When analyzing genes in the largest plasmid, for the first time it is found that the strand-specific mutational biases are responsible for the primary variation of codon usages in plasmid. Genes, particularly highly expressed genes of this plasmid, are mainly located on the leading strands and this supposed to be the effects exerted by replicational-transcriptional selection. These facts suggest that this plasmid adopts the similar mechanism of replication as the chromosome in L. intracellularis. Common characters among the 10 bacteria in whose genomes the strand-specific mutational biases are the primary source of variation of codon usage are also investigated. For example, it is found that genes dnaT and fis that are involved in DNA replication initiation and re-initiation pathways are absent in all of the 10 bacteria.
