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

Due to geometric constraints of planar substrates and poor electrical interface properties, overcoming the performance bottlenecks of single-atom catalysts (SACs) in industrial water splitting remains a challenge. Here, we extend ion implantation technology to hierarchical three-dimensional (3D) structures by constructing iron- and molybdenum-based SACs uniformly anchored on carbon nanotube/nickel foam (CNT/NF) scaffolds. This physical approach enables the precise and scalable incorporation of metal atoms with high dispersion and accessibility on a scale of up to 8 inches. Implantation-induced M─C coordination optimizes the electronic structure of active sites, lowering the reaction energy barrier by shifting the d-band center and enhancing d-p orbital hybridization. Concurrently, the 3D CNT/NF scaffold facilitates rapid charge transfer and efficient bubble release. An anion exchange membrane (AEM) electrolyzer with the two catalysts delivered a current density of 500 mA cm
