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 performance of electrocatalytic oxygen evolution reaction is governed by molecular evolution pathways, yet their regulation remains a significant experimental and theoretical hurdle. Herein, we propose the construction of asymmetric non-metallic dual-active sites through engineering hydroxyl groups in an all-organic electrocatalyst, thereby triggering an uncommon asymmetric oxide pathway mechanism. This reaction pathway reduces the requirement of strict equilibrium on adsorption energies at dual-active sites for traditional oxide pathway mechanism, and also avoids the limitation of the linear scaling relationship for adsorbate evolution mechanism. Therefore, the proposed metal-free electrocatalyst shows competitive oxygen evolution reaction performance with an overpotential of 364.3 ± 4.5 mV at 1.0 A·cm
