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

Kinetin (KT) is a crucial and widely used cytokinin; therefore, its dynamic detection and visualization are of significant importance. In this work, a water-soluble tetralactam macrocycle (TM)-based supramolecular probe was constructed for the in vitro detection and in vivo imaging of KT. Leveraging the excellent recognition of biomimetic TM toward KT, the sensitive and selective "turn-on" fluorescence detection of KT was realized in the range 2-200 μM with a limit of detection of 0.27 μM. The in vitro detection capacity of this supramolecular probe was validated in complex matrices, including potato extract and pesticides. Moreover, a portable visual sensing platform was further developed by integrating the supramolecular probe with hydrogel. Importantly, this supramolecular probe enables monitoring of the concentration distribution of KT through in situ fluorescence imaging, which may provide valuable insights into the physiopathological processes and action mechanisms of KT in plants. Furthermore, a sensor array was developed for discriminating between KT and other structure-similar cytokinins. This method holds great significance for cytokinin-related research.
