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
Environmental pollutants, such as zearalenone (ZEA), a mycotoxin from Fusarium graminearum that contaminates cereal crops and animal feed, significantly threaten reproductive health. The main toxicity mechanism of ZEA involves triggering oxidative stress and apoptosis. Zinc (Zn), a critical antioxidant for reproductive health, may counteract ZEA toxicity, but its mechanism of action remains unclear. The objective of the study was to investigate the alleviating effects of Zn supplementation against ZEA-induced testicular toxicity. We combined network toxicology and animal experiments to evaluate Zn's efficacy. Male Kunming mice were divided into Control, ZEA (2 mg/kg), Zn (20 mg/kg) and ZEA + Zn (10/20/40 mg/kg) groups and treated for 28 days. The results revealed that ZEA exhibited marked reductions in sperm quality, accompanied by structural testicular injury to the testis. ZEA diminishes the activity of the antioxidant enzymes superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px), while simultaneously increasing the levels of malondialdehyde (MDA), which results in oxidative stress. ZEA down-regulates serum levels of testosterone (T), follicle-stimulating hormone (FSH), luteinizing hormone (LH) and impairs steroidogenesis. Significant elevations in ROS levels and apoptotic protein expression were observed in the testicular tissue of the ZEA group. ZEA significantly decreased both the mRNA and protein expression levels of Sirt3 and Foxo3, as well as their immunofluorescence intensity. Zn significantly increased sperm quality, improved testicular morphology, increased Sirt3 and Foxo3 levels, reduced ROS, normalized antioxidant capacity, improved apoptosis, and restored serum hormone levels. These findings emphasize the reproductive risks associated with ZEA, while also highlighting Zn as a possible candidate for developing alleviating effects against mycotoxin-induced reproductive toxicity.
