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

This study demonstrates a one-step hydrothermal synthesis of bright yellow phosphorus-doped carbon quantum dots (P-CQDs) using Caesalpinia sappan L. as carbon source. Comprehensive characterization through TEM, XPS, UV-Vis and FTIRspectroscopy confirmed the successful formation of P-CQDs. The obtained P-CQDs exhibited exceptional selectivity and was capable of detecting ciprofloxacin across a wide linear range of 0.01–0.1 µM, with a LOD determined to be 2.06 nM. Antimicrobial assays revealed MIC values of 7.14 µg/mL and 8.33 µg/mL against S. aureus and E. coli, respectively. Practical application studies confirmed their efficacy for rapid CIP detection in milk samples, establishing a novel sensing platform for food safety monitoring. This work provides valuable insights into the multifunctional applications of carbon dots in food chemistry and biomedical fields.
