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

The hydrogen evolution reaction (HER) in acidic media exhibits high reaction rates but is often hindered by stability challenges under corrosive conditions. In this study, we introduce a novel approach to synthesizing nickel nanoparticles encapsulated in nitrogen-doped carbon layers decorated with noble metals (Ir and Rh), with the aim of improving catalytic activity, durability, and conductivity for HER applications. Using a two-step pulsed laser ablation and irradiation process, this environmentally friendly synthesis facilitates the rapid production of Rh- and Ir-decorated Ni@GC composites with robust metal-support interactions. The resulting catalysts exhibit outstanding HER performance in 0.5 M H
