Perovskite Electrocatalysts for Oxygen Evolution in Alkaline Media: From Fundamentals to Recent Developments.
Review in ChemistryOpen, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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.
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
Carrying out electrolytic water splitting in an alkaline environment permits the usage of transition metal-based electrode materials, compared to the significantly more expensive noble metal-based materials required for electrolysis in an acidic environment. Of the two electrode processes that take place in a water electrolyser, the anodic oxygen evolution reaction (OER) is the bottleneck to the process, due to the sluggish kinetics of the reaction; thus, much research is being directed towards developing electrocatalysts to improve the efficiency of this process. Perovskites are a group of compounds that are emerging as promising OER electrocatalysts due to their low cost, good tunability and high catalytic activity. This review begins with the basic principles and fundamental limitations of the OER before exploring the trade-offs between cost, activity, and durability that are often encountered in electrocatalyst design. Perovskites are then introduced as OER electrocatalysts, with a detailed discussion on structure, activity descriptors, catalyst design strategies, and synthesis methods. A critical review of recent advancements in perovskite materials as OER electrocatalysts is then presented at the end, including the latest developments in heteroatom doping and interface engineering.
