D-galactose treatment accumulates AGEs but induces no further detrimental effects in HR-1 mouse skin.
Article in Experimental animals, 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
As aging affects the appearance of the skin, anti-aging research has intensified in dermatology, skincare, and aesthetic medicine. Because natural aging takes a very long time, one essential anti-aging approach is to pharmacologically mimic aging, such as with D-galactose treatment. Hairless mice (HR-1) have been extensively used in skin research because of their lack of body hair and ease of animal care. In the present study, HR-1 mice were treated with D-galactose to determine whether detrimental effects were induced in the skin. After 3 months of D-galactose treatment, AGEs in the skin significantly increased. On the other hand, no signs of skin disorders (dermal thickness, type I collagen content, expression of various genes, collagen synthesis, and degradation signals) were observed. Even when the concentration of D-galactose increased, no apparent changes in dermal thickness were observed. These findings suggest that D-galactose treatment induces AGEs accumulation but no further detrimental effects in the HR-1 skin.
