Collecting Large Datasets of Unambiguous Structural Restraints for Protein Structure Determination by 4D Proton-Detected Solid-State NMR.
Article in Chemphyschem : a European journal of chemical physics and physical chemistry, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Solid-state magic-angle spinning NMR is a powerful technique for obtaining atomic-resolution structural information of different types of biological macromolecules. The relatively low sensitivity and limited resolution of this method have continuously stimulated methodological developments to broaden its application range. In this study, we efficiently apply proton detection, moderate sample rotation, nonuniform sampling in four-dimensional spectra, multiplexing, deuteration, and stereospecific labeling of methyl groups to collect several hundred unambiguous long-range distance restraints based on proton-proton magnetization transfers. These data provide a reliable description of the core domain structure of full-length bactofilin BacA, which belongs to a newly discovered class of cytoskeletal proteins. The work demonstrates the power of combining available techniques for fast and reliable atomic-level structural investigations that can be applied to a wide range of proteins.
