Personality and cortical architecture in premenstrual dysphoric disorder.
Article in Archives of women's mental health, 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
purposePremenstrual dysphoric disorder (PMDD) has been associated with altered grey matter architecture in a trait-like manner. Personality traits, shaped largely by genetics and linked to depressive disorders, may relate to structural properties of the brain and could represent a potential factor mediating vulnerability for PMDD. However, these possible associations remain largely unexplored.
methodsThe present study assessed personality traits in participants with PMDD and healthy controls, as well as how personality is related to symptom severity and cortical surface measures in PMDD. Healthy controls and patients completed the Swedish Universities Scale of Personality. Following prospective validation of the PMDD diagnosis, patients had their brain scanned with magnetic resonance imaging (MRI) during the symptomatic luteal phase of the menstrual cycle. Personality of controls and patients was compared using Mann-Whitney U tests. Associations of personality with symptom severity and brain surface parameters were tested through correlation analysis.
resultsPMDD was associated with higher scores in neuroticism and aggressiveness. Aggressiveness was positively correlated with the severity of irritability/anger, though not significant after correcting for multiple testing. Regarding cortical structural measures, aggressiveness was negatively correlated with cortical complexity of the parahippocampal gyrus.
conclusionConsidering neuroticism and aggressiveness during screening for PMDD could contribute to the identification of risk factors and personalized treatment of females suffering from PMDD.
