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

Cephalosporins are commonly prescribed antibiotics that impair cross-linking of the bacterial cell wall. The Gram-positive opportunistic pathogen, Enterococcus faecalis, is intrinsically resistant to these antibiotics and proliferates substantially during cephalosporin therapy. As a result, the usage of cephalosporins has the potential to lead to life-threatening enterococcal infections. Yet, the molecular mechanisms that drive cephalosporin resistance (CR) are incompletely understood. Previously, we demonstrated that MurAA, an enzyme that catalyzes the first committed step in peptidoglycan (PG) synthesis, is required for CR. However, the mechanism by which MurAA contributes to CR remained unknown. Here, we tested the hypothesis that MurAA drives CR by controlling metabolic flux through the PG synthesis pathway. To do so, we developed and exploited an inducible gene expression system for E. faecalis based on an interspecies chimeric receptor that responds to exogenous nitrate for control of expression from a NisR-regulated promoter (P
