Effect and mechanism of father's companionship on defensive attack behavior of adult male offspring mice.
Article in Communications biology, 2025. 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
Sociocultural changes in recent decades have promoted fathers' involvement in childcare, which is crucial for the brain and behavioral plasticity of offspring. The study elucidates the effect and mechanism of father's companionship on defensive attack behavior of adult male offspring mice. The study comprises a father companionship group, where offspring cohabited with sire and dam until weaning, and a control group, where offspring cohabited solely with the dam until weaning. The study shows that father's companionship increases defensive attack behavior of adult offspring. Additionally, the metabolite L-aspartic acid is upregulated in the father's companionship group compared to the control group in male offspring, and intracerebroventricular micro-injection of L-aspartic acid confirms its impact on defensive attack behavior. C-Fos immunohistochemistry reveals that c-Fos expression in lateral periaqueductal gray (LPAG) is activated. Subsequently, micro-injection of L-aspartic acid into LPAG increases defensive attack behavior. Additionally, 16S rRNA sequencing reveals a higher abundance of Bilophila and a lower abundance of Bifidobacterium in the father companionship group, which correlates with L-aspartic acid levels, suggesting a gut-brain axis mechanism for the effect of father companionship on defensive attack behavior.
