Caffeine and the Young Heart: A Systematic Review of Arrhythmogenic Risks in Children and Adolescents.
Review in Pediatric cardiology, 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
Caffeine consumption among children and adolescents has increased in recent years, largely through energy drinks. While caffeine is generally considerd as safe in low doses, current evidence suggests that high intake may provoke arrhythmias and electrocardiographic abnormalities in younger populations. This systematic review evaluates the arrhythmogenic effects of caffeine consumption in pediatric and adolescent patients. This review followed PRISMA 2020 guidelines and was registered in PROSPERO (ID 1180917). A systematic search of PubMed, EMBASE, and Cochrane CENTRAL identified studies evaluating caffeine-related arrhythmias in individuals under 19 years of age. Eligible publications included peer-reviewed studies, case reports, and case series reporting arrhythmogenic or electrocardiographic outcomes. Screening and data extraction were performed independently by two reviewers using Covidence. The search yielded 126 articles, of which 12 met the inclusion criteria. These comprised 9 case reports, 1 prospective study, 1 retrospective study, and 1 review including an unpublished case report. Across all eligible studies, a total of 39 adolescents (aged 13-18 years) were reported to have caffeine associated arrhythmias or ECG changes. Caffeine sources included energy drinks, caffeine containing tablets and powdered caffeine. Reported cardiac side effects ranged from sinus tachycardia and premature atrial or ventricular contractions to supraventricular tachycardia, ventricular tachycardia, QTc prolongation and ST-segment abnormalities. This systematic review demonstrates that high dose caffeine from sources like energy drinks, powders and tablets can induce a range of cardiac arrhythmias and electrophysiological abnormalities. Our findings underscore the need for increased awareness and improved public health education regarding the cardiovascular danger of high-dose caffeine in this population.
