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
In the search of sustainable materials for energy storage, phthalimide-based compounds have shown great potential as anolytes for redox flow batteries (RFBs). Here, we conducted a high-throughput computational screening of 5,705 phthalimide derivatives, including a strategically designed subset of biobased candidates derived from renewable platform chemicals. Structure-property analyses, grounded in principles of physical organic chemistry, were employed to elucidate key trends related to redox potential, radical stability, and solubility, properties critical to RFB performance. Statistical modeling and clustering analysis further refined the selection of optimal candidates. From these efforts, a promising biobased compound was identified, and a closely related derivative was synthesized via a sustainable Diels-Alder route. Electrochemical characterization revealed quasi-reversible redox behavior, high solubility in acetonitrile, and exceptional cycling stability over 2,000 redox events without chemical degradation. These results underscore the utility of computational strategies in accelerating the discovery of robust, renewable, and high-performance organic materials for next-generation energy storage systems.
