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

The mechanism of the antimicrobial peptide daptomycin is reviewed and discussed. Daptomycin is a last-resort antibiotic in current use against drug-resistant bacterial infections. Many models have been proposed for its function, most based on the observation that it increases membrane permeability and causes leakage of contents, such as ions and small molecules from bacterial cells and lipid vesicles. However, daptomycin is actually not efficient at permeabilizing or translocating across membranes, contrary to many well-known antimicrobial peptides. There is strong evidence that daptomycin binds preferentially to membranes in active division regions of bacterial cells and that it causes large membrane reorganization in terms of the distribution of lipids and proteins, both in cells and in model membranes. Those observations support the alternative hypothesis for the mechanism of daptomycin that its primary effect is in inducing membrane reorganization and that other events, such as increased membrane leakage and depolarization, are secondary consequences, not essential to its function.
