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

S. aureus is a significant human pathogen and has previously been shown to form cell wall deficient forms or L-forms in vitro and in vivo during infection. Despite many previous studies on S. aureus L-forms, the mechanisms of L-form formation in this organism remain unknown. Here we established the L-form model in S. aureus and constructed a transposon mutant library to identify genes involved in L-form formation. Screening of the library for mutants defective in L-form formation identified glpF involved in glycerol uptake being important for L-form formation in S. aureus. Consistent with this observation, glpF was found to be highly expressed in L-form S. aureus but hardly expressed in normal walled form. In addition, glpF mutant was found to be defective in antibiotic persistence. The defect in L-form formation and antibiotic persistence of the glpF mutant could be complemented by the wild type glpF gene. These findings provide new insight into the mechanisms of L-form formation and persistence in S. aureus and may have implications for development of new drugs targeting persisters for improved treatment.
