FLEth RNA intercalating probe is a convenient reporter for small interfering RNAs.
Article in Journal of the American Chemical Society, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 5 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
Here we report that the phenanthridine derivative covalently linked to a fluorescein moiety (FLEth) can act as a fluorescence based probe for duplex short interfering RNA (siRNA) and that this probe can also be used to report on protein-RNA interactions. A fluorescence resonance energy transfer (FRET) signal that is observed at 600 nm occurs when FLEth is complexed with siRNA. At least 2 molecules of FLEth can bind to 21 nt duplex siRNA, and the dissociation constants for these interactions are reported. We find that FLEth can also report on the interaction of siRNAs with the Carnation Italian ringspot viral suppressor of RNA silencing p19. FLEth does not bind to the siRNA-p19 complex nor can p19 bind to the siRNA-FLEth complex; rather FLEth can report on the fraction of siRNA that is unbound. FLEth can also bind siRNA in delivery systems such as liposomes. Once the siRNA reaches the interior of Huh 7.5 cells, FLEth dissociates from the siRNA and is found in the nucleoli suggesting that FLEth cannot bind to siRNAs that are associated with the RNA silencing machinery.
