Bergamot Leaf Extract Is Associated With Reduced Hepatic DNA Strand Breaks in Diet-Induced Obese Rats.
Article in Environmental and molecular mutagenesis, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Obesity is a major global public health challenge associated with chronic low-grade inflammation and oxidative stress. Although natural antioxidant compounds have been investigated to mitigate obesity-related molecular damage, the effects of bergamot (Citrus bergamia) leaf extract (BLE) on DNA integrity remains unclear. This study evaluated the effects of BLE on hepatic DNA damage in diet-induced obese rats. Forty Wistar rats were fed either a control or a high-sugar-fat (HSF) diet and treated with BLE by oral gavage. The adiposity index was recorded for all groups, and hepatic DNA damage was assessed using the comet assay. The HSF diet significantly increased both the adiposity index and DNA strand breaks in the liver compared with the control group. Notably, BLE treatment was associated with a lower adiposity index and reduced hepatic DNA strand breaks measured by the comet assay in obese rats (p < 0.05). These findings indicate an association between BLE treatment and reduced hepatic DNA damage in this model of diet-induced obesity.
