A pyrene-based two-photon excitable fluorescent probe to visualize nuclei in live cells.
Article in Photochemical & photobiological sciences : Official journal of the European Photochemistry Association and the European Society for Photobiology, 2020. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 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
The two-photon absorption properties of a pyrene-pyridinium dye (1) were studied for potential application in two-photon spectroscopy. When probe 1 was used in cellular two-photon fluorescence microscopy imaging, it allowed the visualization of nuclei in live cells with a relatively low probe concentration (such as 1 μM). Spectroscopic evidence further revealed that probe 1 interacted with DNA as an intercalator. The proposed DNA intercalation properties of probe 1 were consistent with the experimental findings that suggested that the observed nucleus staining ability is dependent on the substituents on the pyridinium fragment of the probe.
