A customised combination of environmental enrichment reduces aggression in CD-1 male mice.
Article in Laboratory animals, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Murine aggression has profound implications on animal welfare and husbandry. This report examines how three distinct combinations of environmental enrichment - wheel, igloo and tunnel; wheel, igloo, and tunnel with nesting; and tunnel with nesting - affect aggressive behaviour in CD-1 male mice. We found that combining wheel/igloo/tunnel enrichment with nesting or replacing the wheel/igloo with two tunnels while maintaining the nesting enrichment reduced aggression. These findings not only suggest how enrichment can improve the welfare of aggressive male mice but also emphasise the need for further research to determine the optimal combination of enrichment.
