Association between neuroticism, genetic susceptibility, and peripheral artery disease risk: a prospective study in UK Biobank.
Article in European archives of psychiatry and clinical neuroscience, 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
backgroundNeuroticism is one of five personality traits characterized by a tendency to generate and intensify negative emotions in the face of stress and is linked to an elevated incidence of cardiovascular disease (CVD). However, the pathogenesis of peripheral artery disease (PAD) differs from other CVDs. This study aimed to investigate the association of neuroticism with PAD and to examine whether genetic susceptibility influences this association.
methods399,730 PAD-free individuals from the UK Biobank were included. Participants were categorized into high (≥ 4 scores) and low neuroticism (< 4 scores) groups based on the median score from a self-questionnaire assessing 12 neuroticism-related behaviors. Cox proportional hazard models were employed to evaluate the association between neuroticism and PAD, as well as the combined and stratified effects of neuroticism and genetic susceptibility on PAD.
resultsAfter a median follow-up of 13.6 years, 4269 (1.1%) participants developed PAD (mean age, 56.4 years; 53.7% female). High neuroticism was associated with significantly increased risk of PAD (hazard ratios [HR] 1.119; 95% confidence interval [CI] 1.051–1.192) compared to low neuroticism. Genetic analyses indicated no significant interaction between genetic susceptibility and neuroticism in relation to PAD (P for interaction = 0.635). Participants with both high PRS and high neuroticism had an HR was 1.451 (95% CI 1.322–1.592) compared to those with low PRS and low neuroticism.
conclusionsHigh neuroticism was associated with an increased risk of PAD, independent of genetic susceptibility. Active mental health monitoring may benefit high-risk populations.
