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
Carbon quantum dots (CQDs) have garnered considerable interest due to their distinctive optical properties, cost-effectiveness, and eco-friendly synthesis routes. This study investigates CQDs synthesized from orange peels through a sustainable hydrothermal method. The CQDs were characterized using UV-Vis spectroscopy, fluorescence spectroscopy, Fourier Transform Infrared (FT-IR) spectroscopy, and transmission electron microscopy (TEM) to elucidate their optical and structural properties. Multi-Gaussian fitting of the photoluminescence (PL) spectra was employed to deconvolute the emission profiles, revealing the contributions of the zero-phonon line (ZPL) and phonon sidebands, which correlate closely with the characteristic carbonyl (C=O) stretching mode at approximately 0.21 eV, as identified by FT-IR. The Huang-Rhys factor, calculated from both the PL spectral analysis and the Stokes shift, quantifies the electron-phonon coupling strength, providing insights into the recombination dynamics. The synthesized CQDs exhibited robust blue fluorescence under UV excitation, with excitation-wavelength-dependent tunable emission. Moreover, the CQDs achieved a significantly enhanced quantum yield compared with previously reported orange peel–derived counterparts, together with stable radiative lifetimes, demonstrating efficient radiative recombination. These features confirm their strong potential for bioimaging, optoelectronic, and sensing applications and reinforce the viability of fruit waste as a sustainable precursor for high-quality fluorescent nanomaterials with well-defined vibronic characteristics.
