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
Background: Personality traits are well-established correlates of anxiety symptoms, yet whether these associations generalize across culturally distinct populations remains insufficiently understood. This study examined the incremental explanatory value of neuroticism and extraversion for anxiety symptoms in a Tibetan sociocultural context after accounting for sociodemographic, health-related, and social-contextual factors. Methods: A cross-sectional survey was conducted among 583 community-dwelling Tibetan adults recruited through convenience sampling in western China. Participants completed the Tibetan adaptations of the Brief Big Five Personality Scale and the Generalized Anxiety Disorder-7 (GAD-7), together with measures of sociodemographic characteristics, mental health history, perceived social support, and religious affiliation. Given the absence of published psychometric validation of the Tibetan adaptation, internal consistency was assessed and an exploratory factor analysis (EFA) was conducted to evaluate the reliability and underlying factor structure of the personality measure. Hierarchical multiple regression and exploratory moderation analyses examined the incremental explanatory value of personality traits and the potential moderating effects of perceived social support and religious affiliation. Results: Neuroticism and extraversion explained an additional 34.3% of the variance in anxiety symptoms beyond sociodemographic and health-related characteristics, increasing the total explained variance from 5.0 to 39.3%. Both traits were positively associated with anxiety symptoms. Perceived social support and religious affiliation contributed negligible additional explanatory value and did not moderate the association between neuroticism and anxiety symptoms. EFA supported a theoretically informed two-factor solution despite substantial overlap between neuroticism and extraversion. Conclusion: Personality traits provided substantial incremental explanatory value for anxiety symptoms in this Tibetan sample. Neuroticism emerged as a robust correlate of anxiety, whereas extraversion was also positively associated with anxiety symptoms, a pattern differing from findings commonly reported in Western populations. These findings highlight the importance of interpreting personality-anxiety associations within their sociocultural and psychometric context and underscore the need for culturally validated personality measures when extending personality research to understudied populations.
