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) is of great importance for the renewable energy conversion to hydrogen fuel via water electrolysis. However, the current benchmark Pt/C catalyst suffers from high cost, pH sensitivity, and deficient durability, severely restricting the large-scale development of membrane water electrolysis. Herein, we develop a cost-effective Pt-free catalyst featuring high-density, ultrafine Ru nanoclusters modified with CoP and uniformly dispersed on nitrogen-doped carbon films (NCF). This catalyst achieves not only superior HER activity across a wide pH range but also robust stability at ampere-level large current densities, manifesting as a competitive alternative to commercial Pt/C. Typically, Ru-CoP/NCF exhibits an overpotential of only 22 mV at 10 mA cm
