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 hybrid molecularly imprinted ratiometric fluorescence probe was constructed based on the characteristic that dicamba (DIC) can brighten the blue fluorescence of Eu-MOFs. According to the change of the fluorescence color of the probe solution from yellow to blue, a smartphone-assisted detection platform was established to realize the visual detection of DIC. The detection limits of fluorescence and smartphone analysis are 0.08 μM and 0.27 μM, respectively. The sensing mechanism study shows that the reaction belongs to the cross-linking fluorescence enhancement effect. Eu-MOFs form hydrogen bonds with the carboxyl groups of DIC and form a dendritic network structure, which inhibits the non-radiative transition of the luminescent center and improves the charge transfer efficiency to achieve enhanced fluorescence. So, this work provides a method for the fluorescence quantitative detection and on-site visual detection of DIC by smartphone in Hordeum vulgare and Setaria italica.
