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 environment and unique balance of molecular forces within lipid bilayers has a profound impact upon the structure, dynamics, and function of membrane proteins. We describe the biophysical foundations for the remarkable uniformity of many transmembrane helices that result from the molecular interactions within lipid bilayers. In fact, the characteristic uniformity of transmembrane helices leads to unique spectroscopic opportunities allowing for phi,psi torsion angles to be mapped directly onto solid state nuclear magnetic resonance (NMR) PISEMA spectra. Results from spectral simulations, the solid state NMR-derived structure of the influenza A M2 proton channel transmembrane domain, and high-resolution crystal structures of 27 integral membrane proteins demonstrate that transmembrane helices tend to be more uniform than previously thought. The results are discussed through the definition of a preferred range of backbone varphi,psi torsion angles for transmembrane alpha helices and are presented with respect to improving biophysical characterizations of integral membrane proteins.
