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

Infections caused by the leading nosocomial pathogen Staphylococcus epidermidis are characterized by biofilm formation on implanted medical devices. In a previous study, we found that ClpP protease plays an essential role in biofilm formation of S. epidermidis. However, the mechanism by which ClpP impacts S. epidermidis biofilms has remained unknown. Here, we show that the Spx protein accumulates in the clpP mutant strain of S. epidermidis and controls biofilm formation of S. epidermidis via a pronounced effect on the transcription of the icaADBC operon coding for the production of the biofilm exopolysaccharide polysaccharide intercellular adhesion (PIA). Notably, in contrast to Staphylococcus aureus, Spx controls PIA expression via an icaR-independent mechanism. Furthermore, Spx affected primary surface attachment, although not by regulating the production of the autolysin AtlE. Our results indicate that ClpP enhances the formation of S. epidermidis biofilms by degrading Spx, a negative regulator of biofilm formation.
