1 · What the graph read from it

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.

2 · The registry

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

Three kinds of N-doped carbon dots (CDs) were synthesized via the solvothermal method using orange juice, lemon juice, and banana leaves as biomass precursors. These CDs exhibited different fluorescence of blue, green, and red with the fluorescence quantum yield (FLQYs) of 16.2%, 14.5%, and 8.4%, respectively. The structure and composition analysis showed that B-CDs and G-CDs were nitrogen doped by urea with the content of about 4%, improving the fluorescence intensity significantly. Notably, the FL of R-CDs were composed of a blue FL emission and a red FL emission, which were inferred to be related to the CDs and chlorophyll-derived porphyrin. Three corresponding CD-based fluorescent inks were prepared by mixing with the thickening agent of glycerol. The application on handwriting, screen printing, and official seal indicated the multilevel UV/visible light dual-mode encryption potential. Furthermore, flexible sensing films were fabricated by incorporating CDs into polyvinyl alcohol (PVA) matrices. Remarkably, the CD-embedded films exhibited significantly enhanced electrical signal responses during mechanical sensing. This work not only provides a novel strategy for high-value utilization of biomass resources but also opens innovative pathways for developing intelligent anti-counterfeiting materials and flexible electronic devices.
