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
Using a variety of biological models, including human cell lines, Salmonella typhimurium, Escherichia coli, and Saccharomyces cerevisiae haploid knockout (YKO) strains, this study aimed to examine the genotoxic effects of gold nanorods (AuNRs). Salmonella and E. coli strains will be cultivated on LB agar plates and incubated for 16 h at 37 °C to perform bacterial tests. The cultures will be subjected to varying quantities of AuNRs after incubation. The comet test will be used to assess the degree of DNA damage in these bacterial strains. Likewise, haploid knockout strains of S. cerevisiae will be grown on YPD plates and incubated at 37 °C for 24 to 48 h before being exposed to different doses of AuNRs for the yeast model. Following treatment, the comet assay will also be used to evaluate DNA damage in yeast cells. The GeneMANIA platform, which offers functional association data to help the interpretation of the genetic findings, will be used to predict protein-protein interaction networks. The HepG2 liver cancer cell line’s expression levels of cancer-related genes will also be examined using real-time PCR. Particular attention was paid to the p53, Bax, and Bcl-2 genes, which are homologous to the chosen yeast genotypes. Findings and outcomes: When compared to untreated control groups, the comet assay findings for both yeast and bacterial cells showed increased tail length, tail DNA percentage, and tail moment, indicating severe DNA damage (P < 0.05). According to a gene expression study, Bcl-2 expression was significantly downregulated, whereas p53 and Bax transcripts were upregulated after being exposed to AuNRs. Analysis of protein-protein interactions provided additional information about the functional arrangement of related proteins. Overall, the results indicate that gold nanorods have genotoxic qualities and lower malignant cell viability.
