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

Membrane protein function within the membrane interstices is achieved by mechanisms that are not typically available to water-soluble proteins. The whole balance of molecular interactions that stabilize three-dimensional structure in the membrane environment is different from that in an aqueous environment. As a result interhelical interactions are often dominated by non-specific van der Waals interactions permitting dynamics and conformational heterogeneity in these interfaces. Here, solid-state NMR data of the transmembrane domain of the M2 protein from influenza A virus are used to exemplify such conformational plasticity in a tetrameric helical bundle. Such data lead to very high resolution structural restraints that can identify both subtle and substantial structural differences associated with various states of the protein. Spectra from samples using two different preparation protocols, samples prepared in the presence and absence of amantadine, and spectra as a function of pH are used to illustrate conformational plasticity.
