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
A new donor-π-acceptor (D-π-A) fluorescent chromophore incorporating an indole-pyrazole donor framework and an electron-accepting unit, 2-(3-cyano-4,5,5-trimethylfuran-2(5H)-ylidene)malononitrile (TCF) was designed. Various active-methylene compounds were also incorporated into the indole-pyrazole donor units to explore the substrate scope of the reaction. The molecular structure was confirmed by spectroscopic techniques, including NMR, FT-IR, and high-resolution mass spectrometry. Their photophysical properties were investigated using UV-Vis absorption and fluorescence spectroscopy in solution, aggregated media, and the solid state. The D-π-A system exhibited weak fluorescence in dilute solution but showed a pronounced aggregation-induced emission/enhancement (AIE/AIEE) effect upon increasing the water fraction in DMSO-water mixtures, accompanied by significantly enhanced fluorescence quantum yields and intense solid-state emission. The enhanced emission is attributed to restricted intramolecular motion in the aggregated state, while efficient intramolecular charge transfer arising from the donor-acceptor framework contributes to their fluorescence behavior. Density functional theory (DFT) calculations on Indole-Pyrazole Donor-Acceptor compounds (IPDA-1 to IPDA-5) further elucidated their electronic structures and supported the experimental photophysical observations. These combined experimental and theoretical results demonstrate that the indole-pyrazole-based D-π-A architecture is an effective molecular platform for developing aggregation-induced emissive luminogens with enhanced solid-state fluorescence and improved quantum yield in the aggregated state highlighting the potential of the synthesized D-π-A fluorophore as a promising candidate for future functional fluorescent materials.
