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

Staphylococcus aureus is a versatile pathogen that shows high levels of inter-strain genetic variability and positive evolution in certain pathogenesis-related genes. Apart from gene content differences, variability in shared genes may affect pathogenicity. Studying such variability requires that the common minimal genome (CMG) be identified. In this study, we have surveyed the CMG of S. aureus with respect to variability amongst orthologous family members, and determined that genes involved in pathogenesis preferentially accumulate variations. A negative correlation between variability of genes and their evolution was found, suggesting a preservation of host-specific function while exhibiting sequence diversity. Variation in key pathogenesis genes in S. aureus might predispose them to functional modulation, thereby playing an important role in evasion of host immunity.
