N-Doped graphene quantum dots (N-GQDs) as fluorescent probes for detection of UV induced DNA damage.
Article in RSC advances, 2022. 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
UV induced DNA damage can lead to the development of skin cancer, skin aging and cell death. In this study, we fabricated a fluorescence-based biosensor that can be applied to the detection of DNA damage caused by UV radiation with the help of nitrogen doped graphene quantum dots (N-GQDs) as the probe material. In this paper, N-GQDs with good fluorescence efficiency have been synthesized by the hydrothermal method and were used as a fluorescent probe for the detection of UV damaged DNA. The fluorescence intensity of N-GQDs was quenched by the static quenching of UV damaged DNA through the formation of a N-GQD/UV damaged DNA complex. Moreover, the effects of different values of pH, NaCl and glucose on analytical performances of the sensor were also studied. Thus, using a fluorescence based approach, we demonstrated a quite simple, rapid, and inexpensive biosensor for the detection of DNA damage caused by UV radiation.
