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

Metal-organic frameworks (MOFs) with tunable coordination environments provide model platforms for elucidating electrocatalytic structure-activity relationships. However, the development of highly efficient MOF-based oxygen evolution reaction (OER) catalysts has been hindered by the limited synthetic control over framework defects and their associated reconstruction pathways. Herein, we report a defect-engineering strategy where a bicarboxylate ferrocene ligand (Fc) and a monocarboxylate linker (benzoic acid, BA) are co-assembled on nickel foam to construct a defect-rich NiFcBA-MOF featuring abundant coordinatively unsaturated Ni sites. Compared to the defect-free NiFc-MOF, NiFcBA-MOF exhibits markedly accelerated electrochemical activation, undergoing rapid in situ transformation into highly active oxyhydroxide species under OER conditions. As a result, NiFcBA-MOF requires only 270 mV of overpotential to reach a current density of 100 mA cm
