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

Water oxidation, widely recognized as the kinetic bottleneck of artificial photosynthesis, limits solar fuel efficiency. Despite progress in elucidating reaction mechanisms and theoretical predictions, the dynamic spatial coupling of charge transfer, localized structural motifs and active-site evolution remains unresolved, particularly as identified under operando conditions, obscuring key mechanistic pathways. Here, by integrating operando electrochemical shell-isolated nanoparticle-enhanced Raman spectroscopy with nanoscale electrochemical reaction imaging, we spatially resolve the atomic-scale interplay between hole transfer dynamics and the evolution of water oxidation intermediates that dictates the reaction kinetics on faceted BiVO
