Spectral Unmixing to Reduce Refraction Effects in Feulgen-Stained Slides.
Article in Sensors (Basel, Switzerland), 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
introductionAs DNA image cytometry and DNA image histology serve as valuable tools in clinical tumor pathology, the need for precise and accurate DNA amount measurements is crucial. This study describes the process of employing spectral unmixing on Thionin-stained slides as a means of reducing refraction effects introduced in the image, during imaging, due to changes in the refraction index within the tissue being imaged.
methodsA correction method that reduces refraction effects on the DNA quantitation measurements by making use of the spectrally limited absorption properties exhibited by Thionin relative to the more spectrally uniform effects of tissue refraction as a function of wavelength.
resultsSpectral unmixing enables an improved estimate of DNA amount at every pixel and a potentially truer representation of the actual distribution of the DNA within individual cell nuclei.
conclusionsSpectral unmixing is a valuable computational technique widely used in histology and cytology research. By reducing refraction-based optical artifacts in the image, it enhances the accuracy of DNA quantitation, minimizes variability, and improves the discriminating ability of nuclear DNA organization as quantified by texture features.
