Age at Coronary Heart Disease Onset, Genetic Susceptibility, and Subsequent Risk of Stroke.
Article in Journal of the American Heart Association, 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
backgroundCoronary heart disease (CHD) has been established as a risk factor for stroke. The study aimed to assess how age at CHD onset influences stroke risk and interacts with genetic predisposition to stroke.
methodsThis prospective cohort study included UK Biobank participants without baseline or pre-CHD stroke. Polygenic risk scores assessed genetic susceptibility. Cox models and propensity score matching investigated the association between CHD onset age and stroke. The interaction analysis was performed using the bootstrap method and likelihood tests. Sensitivity analyses were conducted to ensure robustness.
resultsOver a median follow-up of 15.1 years, 11 180 participants experienced incident stroke. Patients with CHD exhibited higher risks of developing stroke, hemorrhagic stroke, and ischemic stroke than participants without CHD. Notably, each 10-year decrease in onset age correlated with an increased risk of stroke (hazard ratio [HR], 1.27 [95% CI, 1.23-1.32];
conclusionsEarlier CHD onset is independently associated with greater risks of stroke, hemorrhagic stroke, and ischemic stroke, regardless of genetic predisposition. Earlier onset of CHD may serve as a strong independent marker of elevated stroke risk.
