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

Porous carbon spheres (PCSs) were synthesized as a support for nickel nanoparticles (Ni NPs) to fabricate a cathode for hydrogen evolution reaction (HER) in an alkaline electrolyte. Characterization of the material revealed that both non-activated and activated PCS exhibited a porous, spherical morphology without pronounced structural confinement, while the deposited Ni NPs showed a tendency to aggregate into large clusters with an average particle size ranging from 16 nm to 22 nm, depending on the type of the PCS used (non-activated vs. activated). X-ray diffraction and Raman spectroscopy confirmed the predominantly amorphous and defect-rich nature of both pristine (PCS) and activated carbon support (PCS-ACT), providing favorable anchoring sites for metal nanoparticles. Although pristine PCS displayed a higher specific surface area than PCS-ACT (284 ± 10 vs. 143 ± 5 m
