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

Transition metal phosphides (TMPs) are attractive bifunctional electrocatalysts for alkaline water electrolysis. However, their practical deployment is hindered by a fundamental reconstruction paradox. Electron-rich metal-phosphorus frameworks are intrinsically favorable for the hydrogen evolution reaction (HER), whereas efficient oxygen evolution reaction (OER) requires rapid in situ conversion into high-valence metal (oxy)hydroxides-a transformation that is typically kinetically sluggish in conventional TMPs. Here, we report a dynamic pre-catalyst architecture in which electron-enriched Ru nanoclusters are anchored at the interfaces of bimetallic FeCo phosphides (Ru-FeCoP@NF). The Ru nanoclusters act as localized, potential-responsive electron reservoirs, extracting and redistributing electrons from adjacent Fe/Co sites via interfacial charge-transfer pathways. This interfacial electron-pump effect selectively destabilizes the metal-phosphorus framework, markedly reducing the kinetic barrier for OH
