Anthracycline-Induced Cardiomyopathy After Nephro-/Neuroblastoma in Childhood: The Importance of Cardiological Reference Assessment.

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
backgroundLong-term childhood cancer survivors (CCS) may develop anthracycline-induced cardiomyopathy. Our cross-sectional study focused on the question of whether a central echocardiographic reference assessment is associated with a higher detection rate of cardiac dysfunction in a population-based cohort of affected children with neuroblastoma or nephroblastoma. We also examined the prevalence of anthracycline-induced cardiomyopathy and its risk factors. METHODS AND PATIENTS: The cohort of this subproject comprises 370 nephroblastoma or neuroblastoma survivors diagnosed with cancer between 1990 and 2012. At study entry, participants were younger than 18 years old, had been treated with anthracyclines, and had no documented previous cardiac disease. Data were collected via patient questionnaires, cardiologic examinations in the network of adults with congenital heart defects (Erwachsene mit angeborenem Herzfehler [EMAH]) and a reference assessment of the recorded echocardiography.
resultsThe prevalence of cardiomyopathy in the study cohort (mean age: 12 years) was 6.3% at a median of 9.1 years after initial cancer diagnosis. Risk factors were an age under 5 years at tumor diagnosis and concomitant treatment with cyclophosphamide or radiation. As a central and novel finding, the detection rates by the EMAH cardiologists and the reference center are similarly high but discrepant. DISCUSSION: Limitations were mainly due to the low responder rate and incomplete data. This study established a nationwide competence network linking pediatric oncology and cardiology centers across six university hospitals in Germany, enabling data collection on pediatric CCS. Despite lower case numbers compared to adult CCS cohorts, meaningful data were gathered and analyzed.
conclusionCardiac late effects after anthracycline-based therapy in childhood affect a relevant proportion of long-term CCS at pediatric age. In order to enable timely diagnosis and treatment, preventive examinations are essential and might benefit from additional central reference assessments. Discrepancy in detection of cardiomyopathy by reference and EMAH cardiologists requires further investigation.
