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 current investigation was designed as an experimental endeavor to explore the protective efficacy of dehydroepiandrosterone (DHEA) and quercetin against hepatotoxicity induced by copper oxide (CuO) nanoparticles. Rats were subjected to CuO nanoparticle intoxication through intraperitoneal injection of 150 mg/kg b.w. for three weeks, followed by the administration of the aforementioned antioxidants for an additional three weeks. This study systematically tracked alterations in liver enzymatic activity, antioxidant levels, apoptotic markers, and histopathological changes using the comet assay. CuO nanoparticle-intoxicated rats exhibited a significant increase in serum alanine transaminase aspartate aminotransferase (AST), and bilirubin levels, coupled with a noteworthy reduction in serum albumin. Moreover, there was a marked rise in serum tumor necrosis factor-alpha levels, concomitant with a significant decline in serum hepatocyte growth factor (HGF). Caspase-3 and Bax mRNA levels in the serum showed a substantial increase, while serum Bcl-2 mRNA levels witnessed a significant decrease. Liver tissue levels of malondialdehyde (MDA) and nitric oxide (NOx) experienced a significant elevation, and DNA damage was observed through the comet assay. Histopathological examination of the liver tissue substantiated these aforementioned findings. Administration of the antioxidants DHEA or quercetin, either individually or in combination, mitigated the parameters of hepatotoxicity to varying extents. In summary, the hepatic genotoxicity induced by CuO nanoparticles demonstrated improvement following the administration of either DHEA or quercetin. Additionally, their combined administration exhibited a more potent protective potential.
