1 · What the graph read from it

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.

2 · The registry

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

Compositionally complex solid solutions (CCSS), often called high-entropy alloys (HEA) have emerged as a promising platform for electrocatalysts for the hydrogen evolution reaction (HER). However, due to their complexity, the interplay among surface composition, structure, and catalytic activity remains insufficiently understood. Herein, noble-metal-based CCSS thin-film materials libraries, prepared by combinatorial magnetron sputtering, are employed as a platform to elucidate how HER activities of CCSS electrocatalysts are linked to their volume composition through surface segregation and crystal structure. High-throughput investigations of three CCSS material libraries, Ir-Pd-Pt-Rh-Ru, Ag-Au-Pd-Pt-Ru, and Ag-Au-Cu-Pd-Pt, were conducted to assess their structural, compositional, and electrochemical properties, using high-throughput X-ray diffraction (XRD), energy-dispersive X-ray spectroscopy (EDX), X-ray photoelectron spectroscopy (XPS) coupled with Gaussian process regression, and long-range scanning electrochemical cell microscopy (SECCM). Correlative data analysis revealed that the composition-dependent surface segregation, driven by surface energy differences, modulates the distribution of active sites on the surface.
