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 structure of OmpF porin in complex with three common antibiotics (zwitterionic ampicillin, anionic ertapenem, and di-anionic carbenicillin) was determined using X-ray crystallography. The three antibiotics are found to bind within the extracellular and periplasmic pore vestibules, away from the narrow OmpF constriction zone. Using the X-ray structures as a starting point, nonequilibrium molecular dynamics simulations with an applied membrane voltage show that ionic current through the OmpF channel is blocked with bound ampicillin, but not with bound carbenicillin. The susceptibility of Escherichia coli expressing OmpF mutants to ampicillin and carbenicillin was also experimentally characterized using microbiologic assays. These results show that general diffusion by OmpF porins allows for transfer of molecules with varied charged states and give insights into the design of more efficient antibiotics. A better understanding of this mechanism will shed light on nature's way of devising channels able to enhance the transport of molecules through membranes.
