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 is the key reaction in natural and artificial photosyntheses but is kinetically and thermodynamically sluggish. Extensive efforts have been made to develop artificial systems comparable to the natural system. However, constructing a molecular system based on ubiquitous metal ions with high performance in aqueous media similar to a natural system, remains challenging. In this study, inspired by nature, we successfully achieve highly efficient water oxidation in aqueous media. By electrochemical polymerisation of a pentanuclear iron complex bearing carbazole moieties, we successfully integrate two essential features of the natural system: catalytic centre composed of ubiquitous metal ions and charge transporting site. The resulting material catalyses water oxidation with a Faradaic efficiency of up to 99% in aqueous media. Our results provide a strategy to develop catalytic systems for water oxidation.
