Integrating variable centered and person centered approaches for personality and nicotine use.
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
This study explored the relationship between Big Five personality traits and nicotine use, integrating both variable-centered and person-centered approaches to capture the complexity of trait interactions. Data were drawn from a publicly available online survey of 1885 English-speaking adults, categorized as never users (n = 428), former users (n = 582), or current users (n = 875) based on nicotine use. Personality traits were assessed using the Five-Factor Personality Inventory, measuring neuroticism, extraversion, openness, agreeableness, and conscientiousness, with additional data on age, sex, and education. Multinomial logistic regression identified openness, conscientiousness, and agreeableness as significant predictors of nicotine use. Latent Profile Analysis (LPA) revealed four personality profiles: "Ordinary," "Expressive," "Cautious," and "Unstable," with significant differences in nicotine use patterns. The "Unstable" and "Expressive" profiles were associated with current use, while the "Cautious" profile was linked to never use. Sociodemographic factors varied significantly across profiles. These findings underscore the importance of integrating both variable-centered and person-centered approaches to better understand the role of personality traits in nicotine use. Tailored interventions, considering the unique characteristics of each personality profile, may improve nicotine cessation and prevention efforts.
