Paediatric chest pain: evaluating diagnostic testing and clinical outcomes.
Observational study in BMC 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
backgroundChest pain is a common reason for referral to paediatric cardiology clinics. Unlike adults, most paediatric chest pain is benign, yet uncertainty often leads to additional testing. The study aimed to evaluate the aetiology of chest pain in children referred to a tertiary paediatric cardiology clinic, determine the diagnostic yield of additional tests, and identify patients who truly benefit from further investigations using a risk-based approach.
methodsA retrospective observational study of 368 children (5-18 years) presenting with chest pain among 1,631 outpatient visits was conducted. All patients underwent a detailed history, physical examination, and electrocardiogram (ECG). Additional investigations, including echocardiography, chest radiography, and laboratory analysis, were performed selectively based on clinical presentation and red-flag features. Red-flag features were defined as exertional chest pain, syncope, palpitations, abnormal cardiac examination, abnormal ECG, or family history of sudden cardiac death.
resultsCardiac causes were identified in 8 patients (2.2%), whereas 360 patients (97.8%) had non-cardiac aetiology: musculoskeletal (46.2%), idiopathic (24.9%), respiratory (18.8%), gastrointestinal (2.8%), psychogenic (5.8%), and miscellaneous (1.1%). ECG abnormalities were detected in 16 patients (4.3%), echocardiography was positive in 5/208 patients (2.4%), and cardiac biomarkers were abnormal in 2/15 (13.3%). Patients with red-flag features had a significantly higher rate of cardiac diagnoses (13.5% vs. 0.3%). Most additional tests were low-yield in patients without red-flag features.
conclusionMost paediatric chest pain is benign. A structured, risk-based approach using red-flag features helps clinicians identify children requiring further evaluation while potentially reducing unnecessary investigations and optimising resource use.
