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

An ultrafast fluorescent sensor based on polymer dots (PDs) probe was developed for the portable on-site determination of copper (Cu²⁺) contamination in aquatic products. Due to the secondary internal filtering effect (IFE) induced by coordination of Cu²⁺ with polyethyleneimine (PEI) moieties on PDs surface, the probe enabled ultrafast (within 5 s) and highly sensitive (limit of detection of 52 nM) detection of Cu²⁺. Furthermore, an integrated sensing array composed of PDs/poly(vinyl alcohol) (PVA) film was developed, allowing high-throughput and simultaneous analysis of multiple aquatic product samples within 1 min. By combining quick-response (QR) code technology with smartphone-assisted data processing, a multidimensional dataset was established, including Cu²⁺ concentration, testing location, and temporal information. The PDs/PVA film-based monitoring platform offers a comprehensive approach for tracking Cu²⁺ contamination in aquatic products and shows great potential for applications in food safety surveillance and quality management.
