Clinical Spectrum, independent risk factors, and treatment outcomes of pediatric arrhythmias: a multicenter retrospective analysis in Xinjiang.
Article in Frontiers in pediatrics, 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
Background: Pediatric arrhythmias are heterogeneous and differ from adult disease in presentation and management; evidence from geographically vast, resource-variable regions of northwestern China remains limited, particularly in settings where access to pediatric electrophysiology services and prolonged rhythm monitoring is uneven. Objective: To describe the clinical spectrum of pediatric arrhythmias, identify independent risk factors, and assess treatment effectiveness and safety in a multicenter cohort from Xinjiang. Methods: This retrospective multicenter study included children (≤18 years) diagnosed with arrhythmia by ECG and/or 24-hour Holter monitoring in six prefecture-level hospitals in Xinjiang (January 2019 to December 2024). A 1:1 age- and sex-matched healthy cohort served as controls. Candidate factors were screened by univariable chi-square tests and entered into multivariable binary logistic regression; results are reported as ORs with 95% CIs. Management was categorized as regular follow-up, pharmacotherapy, or radiofrequency catheter ablation, with effectiveness assessed using standardized follow-up criteria. Results: We enrolled 232 children with arrhythmia (50.9% male), aged 1.2-18.0 years (mean 11.5 ± 3.6); 68.9% were ≥6 years. Supraventricular arrhythmias were most common (49.1%), and PSVT accounted for 35.3%. In multivariable analysis, congenital heart disease (OR 7.265, 95% CI 4.012-13.298), recent infection exposure (OR 6.452, 95% CI 3.605-11.521), and recurrent arrhythmia history (OR 8.216, 95% CI 4.458-15.169) were independent risk factors (all Conclusions: This Xinjiang multicenter cohort reveals region-specific divergences from published data: higher PSVT (35.3%) and ventricular arrhythmia (24.1%) proportions, and markedly lower ablation utilization (9.5%) vs. tertiary centers in eastern China and internationally. Congenital heart disease, infection exposure, and recurrence history were independent risk factors (ORs 6.5-8.2). Key actionable findings: (1) targeted ECG screening for high-risk children; (2) maintenance of school-based screening for subclinical detection; and (3) effective stratified management with pharmacotherapy and selective ablation, with regional capacity building needed to close the interventional care gap.
