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
Model studies in electrocatalysis provide valuable insights into complex structure-property relationships and rely heavily on experimental techniques that enable the preparation of electrode surfaces with atomic-scale control over morphology. This work investigates the nanopatterning of single-crystalline metal electrodes through ion erosion. On Pt(111), ion erosion produces surfaces with distinct corrugation, characterized by the formation of erosion pits, an equal proportion of (110) and (100) steps, and a high density of kinks. The obtained structural motifs influence the electrochemical behavior of H/OH adsorption/desorption and surface electrooxidation in a unique manner, illustrating that ion-eroded metal surfaces represent a complex but atomically precise platform for exploring the synergistic action of various types of surface defects on the electrode properties. A general applicability of ion erosion is demonstrated by preparing and characterizing ion-eroded surfaces of Ru(0001) and Cu(111), showing that this method can control the density of surface defects in ways that are challenging to achieve through the traditional Clavilier method. Ion erosion enables the imprinting of a variety of surface configurations, ranging from atomically flat to stepped and disordered structures, on a single-crystal substrate, offering new avenues for designing electrodes with tailored reactivity.
