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
The widespread use of silver nanoparticles in many industries is increasing every year. Along with this use, there is growing concern about the potential unintentional exposure of human and animal organisms to these nanomaterials. It has been shown that AgNPs have the ability to penetrate organisms and can have harmful effects on cells and organs in the body. In order to reduce the effects of AgNPs on living organisms, newer solutions are being investigated, such as particle stabilization or other methods of synthesizing these particles. The physical synthesis of AgNPs using high-voltage arc discharge (HVAD) may be one of these alternatives. To determine the effect of silver nanoparticles obtained by this method, cytogenetic analysis was performed on domestic dog somatic cells using a cytokinesis-blocking micronucleus assay. In the experiments performed, peripheral blood cells of the domestic dog were exposed in vitro for 3 and 24 h to three tested colloidal silver compounds (unstable AgNP-HVAD, sodium citrate-stabilized silver nanoparticles-AgNP+C, and silver nitrate). The toxicity of these compounds was evaluated at concentrations of 5, 10, and 20 µg/L, and the presence of the following cellular abnormalities was analyzed: micronuclei, nuclear buds, nucleoplasmic bridges, or multinucleated cells. The study showed a significant increase in the number of micronuclei compared to the control sample, as well as the presence of nuclear buds and nucleoplasmic bridges in somatic cells of the domestic dog, confirming the genotoxic nature of the particles. However, there was no cytotoxic effect due to the lower number of multinucleated cells and the absence of apoptotic or necrotic cells in the samples analyzed. Further studies are needed to better understand the mechanisms of toxicity of AgNPs produced by the HVAD method and the extent of their effects on mammalian somatic cells.
