Epilepsy and incident cardiovascular disease: A prospective UK Biobank cohort study.
Article in BMC 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
backgroundAs a neurological disorder, epileptic seizures have been documented to correlate with structural and functional cardiac alterations in prior studies. However, the long-term risk association between epilepsy and cardiovascular diseases (CVDs) remains incompletely elucidated.
methodsThis prospective population-based cohort study utilized individual-level data from the UK Biobank. The primary composite endpoint comprised incident CVDs, including ischemic heart disease (IHD), heart failure (HF), atrial fibrillation (AF), stroke, and cardiovascular death. Cox proportional hazards regression models with covariate adjustments, complemented by Fine-Gray competing risk analyses, were employed to estimate hazard ratios (HRs) and 95% confidence intervals (CIs) for assessing epilepsy-CVD associations.
resultsA total of 448,487 participants, including 7,220 patients with epilepsy, were included in the analyses. Over a median follow-up of 13.4 years (IQR: 12.5-14.1; range: 3.0-16.2 years), 2,097 (29.0%) and 64,341 (14.6%) participants experienced CVDs in the epilepsy and non-epilepsy cohorts, respectively. Epilepsy was associated with higher risks of overall CVDs (HR: 1.97, 95% CI: 1.88-2.06) and specific cardiovascular outcomes including IHD (HR: 1.63, 95% CI: 1.53-1.74), HF (HR: 1.89, 95% CI: 1.72-2.09), AF (HR: 1.78, 95% CI: 1.65-1.91), stroke (HR: 4.32, 95% CI: 4.01-4.64), and cardiovascular mortality (HR: 2.55, 95% CI: 2.26-2.88), after adjustment for available common variant-based genetic predisposition scores. Furthermore, patients with status epilepticus exhibited a significantly higher CVDs risk compared to those with epilepsy alone (HR: 1.70, 95% CI: 1.43-2.02).
conclusionEpilepsy was associated with higher risks of incident CVDs, including IHD, HF, AF, stroke, and cardiovascular mortality. These findings suggest that patients with epilepsy may represent a population at elevated cardiovascular risk, although causal inference cannot be established.
