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

Precisely modulating lattice oxygen redox to activate the lattice oxygen mechanism (LOM) is paramount for surmounting the constraints of the traditional adsorbate evolution mechanism (AEM) and maximizing the catalytic activity of the oxygen evolution reaction (OER). Herein, we employ an electrochemical reconstruction strategy leveraging a bimetallic MOF precursor (NiPP/NM88B), which undergoes self-optimized in situ transformation into a NiOOH/FeOOH active phase with dense heterointerfaces. The unsaturated metal sites generated at the interfaces elicit interfacial charge redistribution, fortifying Fe─O bond covalency and efficiently activating lattice oxygen to partake in the OER process. Concurrently, the reconstructed active phase synergistically optimizes the adsorption/desorption kinetics of
