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

Cation degradation in ionomers critically limits the durability of pure-water-fed anion exchange membrane water electrolysis, particularly at the anode where high overpotentials and near-neutral pH induce harsh oxidative stress. However, prevailing cation design remains rooted in alkali-stability frameworks, which fall short under these oxidative conditions. Here, a multiscale approach combining molecular degradation and operando diagnostics identifies electrochemical oxidation as the dominant anodic cation degradation pathway in anion exchange membrane water electrolysis, prompting a shift toward oxidation-resistant cation design. Electrolyzers incorporating oxidation-tolerant trimethylammonium-functionalized ionomers achieve 360-hour stability at 1 A cm⁻
