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

A limited-domain ion-imprinted fluorescence sensor (LDIFS) was developed by integrating aptamers with ion-imprinted polymers, achieving exceptional sensitivity and selectivity. Aptamers were immobilized on silanized ZnS quantum dots, after which pre-polymerized potassium dichromate and functional monomers were introduced. The polymerization process generated selective imprinted cavities and stabilized the active conformation of aptamer. LDIFS achieves the detection within 15 min by leveraging the inner filter effect. A dual-recognition mechanism, which integrates conformational locking and imprinted cavity memory, synergistically improves the analytical performance of the sensor. The sensor achieves an ultralow detection limit of 0.43 nmol/L, exhibiting 1-3 orders of magnitude higher sensitivity than conventional approaches. A high selectivity factor of 17.9 was attained, ensuring excellent anti-interference capability. The method was successfully applied to the analysis of real squid samples, yielding recoveries ranging from 85.39% to 102.5% with RSD < 3%. This work presents a highly sensitive and selective strategy for chromium ion detection, showcasing its promising applications in environmental monitoring and food safety analysis.
