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

Uniform ionomer distribution and controlled sulfonate adsorption are critical for low-Pt-loading proton exchange membrane fuel-cell membrane electrode assemblies (MEAs), especially at high current density. In conventional Pt/C catalysts, differences between Pt and carbon surfaces promote sulfonate adsorption on Pt and ionomer aggregation on carbon, thereby limiting proton and oxygen transport. Here we show that a single Co atom dipole layer covering Pt/C (SCDC-Pt) regulates the catalyst-ionomer interface through electrostatic attraction between positively charged Co sites and sulfonate groups. The resulting MEA delivers a peak power density of 1.4 W cm
