A novel animal paradigm of long-term, stress-induced hippocampal atrophy.
Article in Brain medicine : from neurons to behavior and better health, 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
Long-term hippocampal atrophy is a key feature of major depression. In contrast, in rodents subjected to chronic stress there is reversibly decreased hippocampal volume. We show that exposure to seven days of restraint stress alone or with antidepressant treatment combined with a persistent high-fat diet environment lasting 165 days resulted in long-term, stress-induced hippocampal volume reduction in rats, better reflecting the hippocampal shrinkage that is well documented in patients with major depressive disorder.
