The use of effective core potentials in Hirshfeld atom refinement: making quantum crystallography faster in
Article in Journal of applied crystallography, 2025. 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 refinement of structural models against X-ray diffraction data benefits significantly from employing non-spherical scattering factors in terms of precision and accuracy. Tailor-made scattering factors are available from quantum chemical calculations of the electron density using routine calculation packages. In this process, heavy elements in particular pose a difficulty due to their large numbers of electrons which are not involved in chemical bonding. An elegant way to circumvent this is by using effective core potentials. This work presents an approach for the treatment of these missing electrons in advanced structural refinement methods, such as Hirshfeld atom refinement. It also provides examples and benchmarks demonstrating up to a twofold reduction in refinement time without compromising on accuracy.
