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

MurJ, the flippase that exports the bacterial cell wall monomer Lipid II to the periplasm, is a target for new antibiotics, which are desperately needed to treat Gram-negative infections. Quantitative methods to monitor MurJ activity are required to characterize inhibitors but are challenging to develop because the lipid-linked substrate is not chemically altered in a flippase reaction. Here we show that MurJ inhibition can be quantified by measuring the accumulation of intracellular Lipid II using a biotin-tagging strategy. We have exploited this assay to show that MurJ is inhibited in the presence of a compound that dissipates the membrane potential. By probing cysteine accessibility we have found that under this condition MurJ relaxes into an inactive, outward-facing conformation reminiscent of that targeted by the peptide antibiotic Lys
