Personality traits as behavioral determinants of road traffic injury risk: a mechanism-informed cross-sectional analysis.
Article in Frontiers in public 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
Background: Road traffic injuries (RTIs) remain a major global public health burden and a leading cause of mortality, particularly among individuals aged 5-29 years. While environmental and infrastructural determinants have been widely studied, the role of individual behavioral predispositions, including personality traits, remains underexplored. This study examines the association between the Big Five personality traits and RTI risk within a behavioral and injury prevention framework. Methods: A hospital-based cross-sectional study with a case-control analytical framework was conducted in two tertiary centers in Kelantan, Malaysia. Adults aged 18-60 years with RTIs were recruited from emergency departments, while controls were randomly selected from outpatient populations. Personality traits were assessed using the validated Bahasa Malaysia version of the Revised NEO Personality Inventory. A multivariable logistic regression analysis was performed to evaluate the associations between personality traits and RTI risk, adjusting for relevant confounders. Results: A total of 425 participants were included (229 RTI cases and 196 controls) in the study. The RTI group demonstrated marked male predominance. The distribution of personality traits was comparable between the groups. In adjusted analyses, agreeableness and neuroticism were significantly associated with an increased risk of RTIs [OR 1.12, 95% CI (1.03-1.21); OR 1.10, 95% CI (1.03-1.18), respectively]. Conclusion: Personality traits may contribute to RTI risk through behavioral mechanisms involving emotional regulation, attention control, and decision-making. These findings support an integrated model of RTI risk incorporating both behavioral and environmental factors, with implications for targeted road safety and public health interventions.
