Low-Symmetry Face-Capped Fe(II) Tetrahedra Through Anisotropic Ligand Extension.
Article in Angewandte Chemie (International ed. in English), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 6 papers.
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
Low-symmetry cages are attractive metallo-supramolecular targets, as they may possess different characteristics to their higher symmetry analogs. There are no current generalizable routes for the formation of low-symmetry face-capped tetrahedra. We report here a strategy using tritopic tris-bidentate ligands with arms of different lengths to access novel tetrahedra. The use of "isosceles" ligands (two arms the same, one different) gives tetragonal disphenoid structures, while a "scalene" ligand (all three arms different) gives a rhombic disphenoid structure. In this last case, diastereoselectivity is also achieved. Distortion away from a perfect tetrahedron resulted in alteration of the character of the respective cage. More distorted cages were more prone to loss of structural integrity upon introduction of highly coordinating dimethyl sulfoxide solvent into the cage in acetonitrile solution. As well, increasing distortion was shown to increase the ease of oxidation from Fe(II) to Fe(III) within the cages.
