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

This paper describes a simple, qualitative approach for the determination of membrane protein secondary structure and topology in lipid bilayer membranes. The approach is based on the observation of wheel-like resonance patterns observed in the NMR 1H-15N/15N polarization inversion with spin exchange at the magic angle (PISEMA) and 1H/15N heteronuclear correlation (HETCOR) spectra of membrane proteins in oriented lipid bilayers. These patterns, named Pisa wheels, have been previously shown to reflect helical wheel projections of residues that are characteristic of alpha-helices associated with membranes. This study extends the analysis of these patterns to beta-strands associated with membranes and demonstrates that, as for the case of alpha-helices, Pisa wheels are extremely sensitive to the tilt, rotation, and twist of beta-strands in the membrane. Therefore, the Pisa wheels provide a sensitive, visually accessible, qualitative index of membrane protein secondary structure and topology.
