Dose- and tissue-dependent effects of cannabidiol on antioxidant status in developing chicken embryos.

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
This study investigated the dose- and tissue-dependent effects of cannabidiol (CBD) on the antioxidant status of developing chicken embryos, a key model for vertebrate development. Fertilized eggs were administered CBD (2, 10, or 20 mg/kg egg weight) on the sixth day of incubation. Tissues (brain, liver, heart, thigh muscle, intestine) were collected on day 13 and analyzed for glutathione (GSH), glutathione peroxidase (GPx), superoxide dismutase (SOD), and malondialdehyde (MDA). The results demonstrated potent, tissue-specific effects. CBD exhibited its strongest antioxidant activity in the liver, where 10 mg/kg significantly increased GPx and SOD activity and reduced MDA by ~ 44%. In the brain, it enhanced antioxidant enzymes and decreased lipid peroxidation. Conversely, the high dose (20 mg/kg) increased oxidative stress in cardiac tissue, elevating MDA by 27%. Striated and smooth muscles showed more moderate responses. These findings highlight CBD's tissue-specific and dose-dependent antioxidant properties, underscoring its potential benefits in the liver and brain but cautioning against high doses due to cardiac risks. Further research is needed to elucidate the mechanisms and long-term implications of CBD exposure during embryonic development.
