Dual Metal Synergy-Induced d-Band Modulation in ZIF-7 Nanosheets for Efficient pH-Universal Electrocatalytic Hydrogen Evolution.
Article in Chemistry, an Asian journal, 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
The development of robust and cost-effective electrocatalysts for the hydrogen evolution reaction (HER) across universal pH remains a practical challenge due to sluggish kinetics, low electrical conductivity, and poor structural rigidity of pristine MOFs. Herein, an approach has been proposed to improve the electrocatalytic properties of ZIF materials by electronic modulation via systematic Fe doping, which serves as an active site for hydrogen adsorption and stabilizes HER intermediates within the 2D ZIF-7 framework. The optimized electrocatalyst preserves the pristine ZIF-7 (III) 2-D morphology upon Fe-doping, with a stacked layered nanosheet morphology that has been investigated for HER performance across universal pH conditions. The optimized 15% Fe-doped ZIF-7 (15Fe-ZIF-7) exhibits superior HER activity in both alkaline and acidic media compared to pristine ZIF-7 and 5Fe-ZIF-7, with overpotentials of 79.9 and 93.5 mV at -10 mA cm
