The relationship between personality dimensions and addiction type in women addicted to alcohol and opioids.
Article in Scientific reports, 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
Personality traits significantly influence the development, persistence, and treatment outcomes of substance use disorders. Despite increasing addiction rates among women, sex-specific research remains limited. This study explores the relationship between addiction type and personality traits among inpatient women addicted to alcohol and opioids. A cross-sectional design included three groups: 80 women with alcohol addiction, 80 with opioid addiction, and 80 healthy controls. Participants completed the Revised Temperament and Character Inventory (TCI-5-R) and the Revised NEO Personality Inventory (NEO-PI-R). One-way ANOVA assessed group differences, and canonical discriminant analysis predicted group affiliation. Women with opioid addiction showed a distinct and maladaptive personality profile on both inventories compared to women with alcohol addiction and healthy controls, whereas women with alcohol addiction more closely resembled controls. According to Cloninger's model, opioid-addicted women scored significantly higher on Novelty Seeking and Self-Transcendence, and lower on Self-Directedness and Cooperativeness (p < 0.001). Within the Five-Factor Model, they also scored higher (p < 0.001) on Neuroticism and lower on Agreeableness and Conscientiousness compared to alcohol-addicted women. Personality differences were more pronounced between women with opioid versus alcohol addiction than between alcohol-addicted women and healthy controls.
