Nickel and Ferrocene as Catalyst Candidates to Promote an Effective Oxygen Evolution Reaction.
Article in ACS omega, 2025. 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
The oxygen evolution reaction (OER) is the main bottleneck in water splitting and other key technologies due to its slow kinetics. The development of low-cost, highly active, stable, and more efficient electrocatalysts as an alternative to the commonly expensive and scarce Ir- and Ru-based catalysts used is necessary. The present work reports the preparation of OER catalysts by a straightforward and easy method based on the synergistic effect of Ni/Ferrocene combination that leads to high current densities, lower overpotential, high stability, and low Tafel slope in alkaline conditions. The optimized Ni/Ferrocene catalyst demonstrates exceptional performance, providing a constant potential of ∼1.51 and ∼1.65 V and overpotentials of ∼0.278 and ∼0.420 V for more than 26 and 46 h at current densities of 10 and 100 mA·cm
