Synthesis of ethynylated phenothiazine based fluorescent boronic acid probes.
Article in Journal of fluorescence, 2011. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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.
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
Ethynylated phenothiazine based fluorescent boronic acid probes were prepared. Sonogashira coupling reaction was used to introduce substituted phenylethynylene fragments to the phenothiazine fluorophore to extend the π-conjugation and to enhance the emission property. The photophysical properties and the binding properties of these probes with hydroxyl acids were investigated. We found that the probes with significant ICT effect show emissions which are sensitive to solvent polarity. The phenothiazine moiety is proved to be electron-donating. We found the substitution profile imparts significant effect on the photophysical properties of the probes. For example, one of the probes shows d-PeT effect, whereas the regioisomer probe with similar π-conjugation fragment but different substitution profile shows the a-PeT effect. The easy derivatization of phenothiazine fluorophore, the structure-photophysical property relation and the novel d-PeT fluorescence transduction profile of the phenothiazine based probes described herein may inspire more investigation into this fascinating research area.
