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

High-entropy-alloy (HEA) nanocrystals offer tremendous potential as next-generation catalysts for complex electrochemical reactions. Nonetheless, there is a relative dearth of attention regarding the structural evolution of HEAs under electrochemical conditions. We herein used platinum-group HEA nanocubes, initially enclosed by well-defined {100} facets, as electrocatalysts for the multistep ethanol oxidation reaction (EOR). Notably, the prepared catalysts demonstrate an 8.3-fold enhancement in specific activity during electrochemical cycling, driven by the structural evolution of catalyst facets. This transformation leads to a severely beveled cubic morphology characterized by an approximately equal distribution of {100}, {110}, and {111} facets, while preserving the compositional homogeneity and high-entropy nature, as confirmed by high-resolution transmission electron microscopy and synchrotron-based x-ray absorption spectroscopy. In situ surface-enhanced infrared absorption spectroscopy, electrochemical stripping experiments, and computational calculations reveal that the enhanced performance originates from improved C─C bond cleavage and superior resistance to poisoning by formate intermediates (HCOO
