Trait impulsivity and risk of cardiovascular disease over 8 years: results from the NutriNet-Santé cohort.
Article in European journal of epidemiology, 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
Cardiovascular disease (CVD) remains the leading global cause of death, despite being partially preventable. Emerging evidence suggests psychological traits, such as trait impulsivity, may influence disease onset. However, associations between impulsivity and CVD remain understudied. This study investigates associations between trait impulsivity and CVD incidence. We conducted a prospective analysis within the French NutriNet-Santé cohort between May 2014 (time of impulsivity assessment) and February 2023, including adults aged ≥ 18 years without prevalent CVD. Data were collected via a web-based platform. Trait impulsivity was assessed using the Barratt Impulsiveness Scale 11 and categorized as low, moderate (reference), or high. Incident CVD events, including coronary heart disease and cerebrovascular disease, were identified through follow-up assessments and confirmed by NutriNet-Santé experts using medical records. Multivariable Cox proportional hazards models estimated hazard ratios and 95% confidence intervals (HR [95%CI]). Potential interactions, such as prevalence of type 2 diabetes (T2D), were assessed. Among 48,135 participants (78.1% women; mean age: 50.5 ± 14.5 years), 1,184 developed CVD over a median follow-up period of 7.84 years (IQR: 4.04-8.50). High impulsivity was associated with increased CVD risk (HR = 1.27 [1.01, 1.59], P = 0.039), compared to moderate impulsivity. Among participants with T2D (n = 1,301), low impulsivity was associated with reduced CVD risk (HR = 0.42 [0.20, 0.88], P = 0.022); no such association was observed in those without T2D (P for interaction = 0.014). Higher trait impulsivity was associated with greater CVD risk, while lower impulsivity exhibited protection in individuals with T2D. Trait impulsivity may represent a relevant psychological risk factor for CVD and could inform prevention strategies.
