Preparation and Photophysical Characterization of N‑Substituted 7‑Nitro-2,1,3-benzoxadiazol-4-amine Derivatives.
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 7-nitro-2,1,3-benzoxadiazole (NBD) scaffold is a widely studied and well-respected fluorophore. It is used in many sensing and imaging applications, both as an independent molecule and in larger molecular systems as a fluorescent building block. The broad applicability of NBD is due to its small size and respectable photophysical properties. To integrate this scaffold into these larger systems, NBD is often converted into 4-amino NBD with a spacer group that then acts as a bridge to connect it to the rest of the molecule. While many examples of these systems exist, this story seeks to expand the library of 4-amino NBD derivatives available for future use in more complex molecular systems. This study highlights the synthesis of one new compound, a new synthesis of a previously reported compound, and the photophysical characterization of each in several solvents.
