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

Building on the precursor probe BMQ-1 with A-π-A configuration, a new optimized fluorescent probe, XYT, for the determination of sulfur dioxide was developed by extending the π-conjugation through replacing the electron acceptor 1-(4-dimethylaminophenyl)-2-cyanoacrylonitrile with 1-(7-diethylaminocoumarin-3-yl)-2-cyanoacrylonitrile. This modification resulted in a redshift of XYT in emission wavelength from 590 nm to 603 nm upon reaction with sulfite. The probe demonstrated rapid colorimetric and fluorogenic changes (≈ 10 s), with the solution turning from colorless to red and emitting strong red fluorescence. XYT exhibited high selectivity, photostability, and sensitivity, achieving a detection limit as low as 49.9 nM. In practical detection scenarios, XYT was adopted to measure residual SO
