Population-based screening for conditions associated with juvenile sudden cardiac death: a systematic review and meta-analysis.
Synthesis in European heart journal. Quality of care & clinical outcomes, 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
aimsJuvenile sudden cardiac death (SCD) is predominantly caused by inherited or congenital heart conditions. While structured screening programmes for competitive athletes are well established, current international guidelines emphasize a gap of evidence regarding the value of mass screening in the general youth population. This systematic review aimed to assess the effectiveness of large-scale screening programmes in detecting conditions associated with SCD among young individuals. METHODS AND
resultsWe conducted a systematic review following PRISMA guidelines, with the protocol registered in PROSPERO (CRD42024540606). Original studies evaluating cardiovascular screening in young individuals were included, while studies exclusively involving competitive athletes were excluded. Nineteen studies encompassing 1 079 781 participants from multiple countries were finally analysed. Most studies (68%) were published recently and primarily targeted children and adolescents aged 6-19 years; 63% were assessed as having a low risk of bias. Screening modalities included electrocardiography (ECG) alone (26.3%), questionnaires alone (5.3%), and a combination of both (68.4%). Following second- or third-line investigations, the overall diagnostic yield for SCD-risk conditions was 1.4‰ (1.9‰ in the meta-analysis). The pooled prevalence, estimated using a random-effects model, was 2.23‰ (95% CI: 0.94-5.29‰), with extremely high heterogeneity among studies (I2 = 100%, P < 0.0001).
conclusionSystematic cardiovascular screening may help identify young individuals at increased risk for SCD, providing a potentially meaningful diagnostic yield. However, the absence of long-term data on outcome and cost-effectiveness underscores the need for further research to refine screening protocols, assess sustainability, and inform evidence-based public health policies.
