1 · What the graph read from it

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.

2 · The registry

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

Our early work suggested that graphene quantum dots (GQDs) block Cu(II)/Cu(I) redox cycle in biological systems. Here we report that GQDs could also potently protect against copper redox-mediated oxidative DNA damage. Using Cu(II)/hydrogen peroxide, Cu(II)/hydroquinone, and Cu(II)/ascorbic acid as three biologically relevant systems for inducing oxidative DNA damage, we demonstrated that GQDs protected against the above system-induced DNA strand breaks in ϕx-174 plasmid DNA in a concentration-dependent manner. Notably, a significant protection was observed with GQDs at 1 μg/ml, and a nearly complete protection was shown with 10 and 100 μg/ml of GQDs. Using electron paramagnetic resonance (EPR) spectrometry in conjunction with α-(4-pyridyl-1-oxide)-
