Risk of atrial fibrillation according to electrocardiographic risk factors: a nationwide cohort study of 1.5 million patients.
Article in European heart journal open, 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
Aims: Atrial fibrillation (AF) is associated with an increased risk of stroke, yet no evidence exists on the collective effect of electrocardiogram (ECG) risk factors in early detection of AF. We aimed to evaluate the risk of new-onset AF and stroke according to specific ECG risk factors to identify patients at high risk of developing AF. Methods and results: We included patients who had an ECG performed and grouped them according to how many of the following ECG risk factors they presented with: Elevated heart rate at rest, prolonged PR-interval, biphasic P-waves, abnormal P Conclusion: The selected ECG risk factors were commonly observed. The 5-year incidence of AF and stroke was low among patients with no ECG risk factors, yet increased in a dose-response-like manner according to the number of ECG risk factors. Scoring patients according to simple ECG risk factors effectively identified patients at high risk of AF and stroke.
