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

Balancing the activity and stability of catalysts has become one of the key approaches to breaking through the bottleneck of ampere-level water electrolysis. Oxygen vacancies are one of the most important active structures in catalysts. The complex structure of oxygen vacancies, such as the spatial distribution, profoundly affects the catalytic activity and mechanism. Here, we present a mechanochemical method that utilizes controlled environment pressure to create oxygen vacancies and modulate their spatial distribution in Pr
