Characterisation and prognostic implications of the 12-lead electrocardiogram in children with RASopathy-associated hypertrophic cardiomyopathy.
Article in Heart (British Cardiac Society), 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
backgroundThe 12-lead ECG is a simple, inexpensive clinical tool with a key role in the assessment of patients with hypertrophic cardiomyopathy (HCM). The aims of this single centre, retrospective cohort study were to characterise ECG findings and to identify potential ECG predictors of major adverse cardiovascular events (MACE-cardiovascular mortality, resuscitated cardiac arrest, ventricular arrhythmias with haemodynamic compromise, appropriate implantable cardioverter defibrillator therapy or heart failure hospitalisation) in children with RASopathy-associated HCM (RAS-HCM).
methodsThe resting 12-lead ECGs of 84 children with RAS-HCM were compared with those from 113 patients with sarcomeric HCM (s-HCM).
resultsA significant proportion of ECGs in RAS-HCM had superior axis deviation (29.8% vs 2.5%, p value<0.001) and voltage criteria for right ventricular hypertrophy (52.4% vs 28.3%, p value<0.001), and a significantly lower prevalence of pathological Q waves (27.4% vs 47.8%, p value<0.001). Over a median follow-up period of 6.8 years (3.1-9.7), 19 patients (22.6%) with RAS-HCM suffered an MACE. Right atrial enlargement and ST segment changes>2 mm correlated with MACE on univariate analysis, with the latter remaining significant after adjustment in a multivariate model (adjusted relative risk (RR) 2.33, 95% CI 1.12 to 4.86, p value 0.024).
conclusionThese findings suggest that the 12-lead ECG may be a useful screening tool to distinguish RAS-HCM from s-HCM in everyday practice and could have potential implications for prediction of adverse outcomes.
