PR Interval and the Risks of Recurrent Syncope and All-Cause Mortality in Patients Presenting With Syncope.
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
backgroundRisk assessment of patients with syncope does not consider a short PR interval despite its association with increased risk of atrial fibrillation and all-cause mortality. This study aimed to explore the association between the PR interval and all-cause mortality and recurrent syncope in patients admitted to the hospital with syncope.
methodsWe included patients with a diagnosis of syncope and an ECG recorded within 24 hours of hospital admission from the Danish Nationwide Electrocardiogram Cohort and divided patients into short (<120 ms), normal (120-200 ms), or long PR interval (>200 ms). Patients with ECG abnormalities or comorbidities influencing the PR interval or outcomes were excluded.
resultsA total of 52 038 patients were included. Adjusting for age, sex, and relevant covariates the highest hazard ratio (HR) was observed in patients with short PR interval with an HR of 1.50 (95% CI, 1.24-1.80,
conclusionIn patients with syncope, a short PR interval was associated with higher risk of all-cause mortality; however, a long PR interval was associated with increased rate of recurrent syncope.
