Prevalence and Clinical Significance of Short PR Interval in 1310 Children and Adolescent Athletes: A Cross-Sectional Study.
Article in Sports medicine - 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
backgroundChildren and adolescents represent a challenging population due to their incomplete physical development, and lack of specific criteria for interpreting electrocardiography (ECG) in children and adolescent athletes. We aimed to investigate the prevalence and clinical significance of short PR interval in pediatric and adolescent athletes undergoing pre-participation cardiac screening.
methodsThis is a cross-sectional study, where a total of 1310 athletes (age range: 7-18 years) underwent a comprehensive screening including medical history, physical examination, 12-lead ECG, echocardiography, and exercise testing under stress at Exercise and Sports Medicine Unit, University of Molise, Campobasso Italy between January 2023 and June 2024. Short PR interval prevalence and clinical significance were evaluated by frequency analysis and association with cardiac symptoms, respectively.
resultsShort PR interval (< 120 ms) was present in 26.9% of athletes, while using a z-score threshold of - 2 as the age- and sex-adjusted lower limit of normal, 3.82% of the athletes met criteria for a short PR interval. No significant associations were found between short PR interval and cardiac symptoms: syncope, palpitations, chest pain, exercise-induced arrhythmias, or need for additional diagnostic testing beyond standard screening (p > 0.05).
conclusionsIsolated short PR interval was not associated with adverse cardiac findings among children and adolescent athletes following pre-participation screening, supporting its interpretation as a benign age-dependent variant. However, long-term outcome data are needed to confirm these observations.
