2D Electron Crystallography of Membrane Protein Single-, Double-, and Multi-Layered Ordered Arrays.
Article in Methods in molecular biology (Clifton, N.J.), 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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.
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 electron cryo-microscopy (cryo-EM) approach of 2D electron crystallography allows for structure determination of two-dimensional (2D) crystals of soluble and membrane proteins, employing identical principles and methods once 2D crystals are obtained. Two-dimensional crystallization trials of membrane proteins can result in multiple outcomes of ordered arrays, which may be suited for either 2D electron crystallography, helical analysis, or MicroED.The membrane protein 2D crystals used for 2D electron crystallography are either single- or double-layered ordered proteoliposome vesicles or sheet-like membranes. We have developed a cryo-EM grid preparation approach, which allows for the analysis of stacked 2D crystals that are neither suitable for MicroED nor for directly applying 2D electron crystallography. This new grid preparation approach, the peel-blot, uses the capillary force generated by submicron filter paper and mechanical means for the separation of stacked 2D crystals into single-layered 2D crystals, for which standard 2D electron crystallography can then be employed. The preparation of 2D crystals, the peel-blot grid preparation, and the structure determination by 2D electron crystallography are described here.
