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

Addressing the activity-durability trade-off of low-iridium anode catalysts remains a key challenge for acidic oxygen evolution reaction (OER) in proton exchange membrane water electrolysis (PEMWE). Herein, we develop a three-dimensional ordered macroporous (3DOM) Cr─Ir solid solution oxide to regulate intersite oxygen intermediate reactivity for efficient and durable acidic water oxidation. Solid solution formation, together with the ordered macroporous architecture, creates electronically and geometrically coupled Cr─Ir dual sites that enable a potential-triggered coupling between the conventional adsorption evolution mechanism (AEM) and the oxide pathway mechanism (OPM). Beyond the AEM pathway involving *OOH intermediates at Ir sites, anodic polarization activates surface Cr─OH species into Cr─O moieties that cooperate with adjacent Ir─O species to promote intersite O─O coupling, thereby preserving the structural robustness associated with AEM while harnessing the activity advantage of OPM. As a result, Cr
