Polarization sensing of fluorophores in tissues for drug compliance monitoring.
Article in Analytical biochemistry, 1999. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
We used a new method, polarization sensing, to monitor the concentration of the fluorophore rhodamine 800 in an intralipid suspension and in chicken tissue. Rhodamine 800 (Rh800) could be excited at 648 nm using a laser pointer. We developed a simple device for measuring the combined emission from a highly polarized reference film and the unpolarized or orthogonally polarized emission of Rh800 from the scattering intralipid or tissue. The concentration of Rh800 in this medium was revealed by large changes in the polarization (P) with values of P ranging from 0.8 to -0.9. It is possible to vary the sensitive Rh800 concentration range by variation of the detected emission wavelengths, orientation of the excitation polarizer, or fluorophore concentration in the reference film. Polarization sensing of fluorophores in tissue requires only steady-state detection, and can be accomplished with simple and/or portable electronics. Such devices may find use in electronic detection of ingested medicines based on transdermal detection of nontoxic long-wavelength fluorophores.
