Fluorophore-mediated Photooxidation of the Guanine Heterocycle.

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
Fluorescent dyes are routinely used to visualize DNA or RNA in various experiments, and some dyes also act as photosensitizers capable of catalyzing oxidation reactions. The present studies explored whether the common labeling dyes fluorescein, rhodamine, BODIPY, or cyanine3 (Cy3) can function as photosensitizers to oxidize nucleic acid polymers. Photoirradiation of each dye in the presence of the guanine (G) heterocycle, which is the most sensitive toward oxidation, identified slow rates of nucleobase oxidation in the nucleoside and DNA contexts. For all four fluorophores studied, the only product detected was spiroiminodihydantoin (Sp) suggesting the dyes functioned as Type II photosensitizers and generate singlet oxygen (
