Overcoming Imaging Limitations: 4D-STEM Pair Distribution Function for Resolving Structure of Supported Pt
Article in Small methods, 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
Metallic clusters in the 2-200 atom range exhibit exceptional functional properties arising from their large fraction of under-coordinated surface sites and quantum size effects. However, structural characterization of these clusters is challenging due to the absence of well-defined periodicity and long-range crystal structure. In this size regime, surface and finite-size effects dominate, leading to highly relaxed and/or multiply twinned configurations minimizing total energy. Experimental approaches using x-rays and electrons require particular care, as irradiation can distort the intrinsic structure of these clusters. To accurately resolve their structure, probing techniques must operate at sufficiently low dose to avoid atomic displacement from equilibrium sites. Here, we investigate the structure of Pt
