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

NiFe-layered double hydroxides (LDHs) are promising electrocatalysts for the oxygen evolution reaction (OER) in alkaline media. Here, operando X-ray diffraction (XRD) and X-ray total scattering are used with Pair Distribution Function (PDF) analysis to investigate the atomic structure of the catalytically active material and follow structural changes under operating conditions. XRD shows an interlayer contraction under applied oxidative potential, which relates to a transition from the α-LDH to the γ-LDH phase. The phase transition is reversible, and the α-LDH structure is recovered at 1.3 VRHE. However, PDF analysis shows an irreversible increase in the stacking disorder under operating conditions, along with a decrease in the LDH sheet size. The analysis thus shows that the operating conditions induce a breakdown of the particles leading to a decrease in crystallite size.
