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

Electrocatalytic hydrogen evolution reaction (HER) offers a sustainable pathway for green hydrogen production, addressing growing energy demands while reducing fossil fuel dependence. However, existing electrocatalysts face challenges, including low current densities, excessive Pt reliance, and inefficient charge transfer. Here, ampere-level HER catalysis is achieved by introducing 2D nanoelectrode superlattices that boost electrocatalytic efficiency through two key concepts: i) Electric field amplification, where Ag nanoparticles serve as nanoelectrodes and their interparticle interactions within the superlattice are leveraged to concentrate local electric fields for facilitating charge accumulation and transfer. ii) Intermetallic Pt-Ag hybridization, which modulates electronic structure and electron distribution to enhance intrinsic catalytic activity. Notably, Ag hexagonal@Pt achieves the highest performance, delivering -15.88 A cm
