1,4-Dihydropyrrolo[3,2-b]Pyrroles Containing New A-D-A System: Synthesis and Investigation of Their Photophysical Properties.
Article in Journal of fluorescence, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Herein, new tetraarylpyrrolo[3,2-b]pyrroles (TAPP) containing different substituents (4a-c, 5a-c) on the N-phenyl rings were synthesized in high yields using a one-pot method. The 3,6 positions of the pyrrolopyrol ring of the 4a-c compound were formylated by Vilsmeier-Haack reaction to synthesize a new pyrrolopyrol compound containing the acceptor-donor-acceptor (A-D-A) system (5a-c). The photophysical properties of all obtained derivatives were investigated in different solvents. According to the results obtained, the absorptions of derivatives 4a-c were recorded around 400 nm and their emission intensities appeared around 450 nm. The absorption intensities of derivatives 4b and 5b were recorded as 400 nm and 350 nm, respectively, while their emission intensities were observed as 455 and 440. In the A-D-A system formed as a result of the bonding of electron-withdrawing formyl groups at position 3,6 of the TAPP structure, a high Stokes shift occurred, while 50 nm hypsochromic shifts were observed in its absorption.
