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
Adolescent alcohol abuse in disadvantaged communities is a significant concern due to regulatory gaps. It disrupts brain development, particularly affecting the hippocampus, which is vulnerable to alcohol-induced oxidative stress, resulting in impaired neuronal signalling, increased cell death, and reduced neurogenesis. Simvastatin, a cholesterol-lowering drug, has neuroprotective and antioxidant effects, but its potential in protecting against alcohol-related brain damage is unclear. This study examined the protective effects of Simvastatin in four-week-old C57BL/6J mice administered 20% alcohol (intraperitoneal, i.p.), 5 or 15 mg/kg Simvastatin orally, followed by 20% alcohol (i.p.) or the controls (i.e., 5 mg/kg Simvastatin only or no treatment). After 28 days, the harvested brains underwent biochemical or immunohistochemical (IHC) analysis. Biochemical analyses measured malondialdehyde (MDA) levels, glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activity in homogenised hippocampal samples and IHC involved immunolabelling for PcNA or DCX. PcNA- or DCX-positive cells in the suprapyramidal blade of the dentate gyrus were counted using QuPath software. Alcohol elevated GSH-Px activity, indicating oxidative damage, but both Simvastatin concentrations reduced this, with 15 mg being more effective in females. MDA level and SOD activity remained unchanged. Simvastatin at 5 mg reduced alcohol's effect on PcNA-positive cells in both sexes, while 15 mg was more effective in females. For DCX-positive cells, 5 mg Simvastatin was protective in both sexes, but 15 mg showed no effect. Overall, Simvastatin exhibited antioxidant and neuroprotective effects against alcohol-induced hippocampal damage, suggesting its potential for treating alcohol-related brain disorders.
