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

sThe role of Panton-Valentine leukocidin (PVL) in Staphylococcus aureus pathogenesis is controversial. Here, we show that an unintended point mutation in the agr P2 promoter of S. aureus caused the phenotypes in gene regulation and murine pneumonia attributed to PVL by earlier investigators. In agreement with other studies that failed to detect similar effects of PVL using community-associated methicillin-resistant S. aureus strains, we found no significant effect of PVL on gene expression or pathogenesis after we repaired the mutation. These findings provide further evidence that PVL does not have a major impact on S. aureus pathogenesis. Moreover, our results demonstrate that a single nucleotide polymorphism in an intergenic region can dramatically affect bacterial physiology and virulence. Finally, our work emphasizes the need to frequently evaluate the integrity of the S. aureus agr locus.
