Predicting the 10-year risk of cardiomyopathy in long-term survivors of childhood cancer.

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
backgroundConsidering the heightened risk of cancer treatment-related cardiomyopathy and cardiac death in long-term survivors of childhood cancer, we aimed to develop and validate a clinically applicable risk prediction model for cardiomyopathy. PATIENTS AND
methodsChildhood cancer survivors from the St. Jude Lifetime Cohort, [SJLIFE, model-development; n = 3479; median age 32.3 years, interquartile range (IQR) 24.4-40.9 years] and the Childhood Cancer Survivor Study (CCSS, model-validation; n = 6875; median age 33.2 years, IQR 27.9-38.9 years) were assessed for demographic and cardiovascular risk factors, treatment exposures, and polygenic risk scores (PRSs) for cardiomyopathy, heart failure, cardiac structure and function, and anthracycline-related cardiomyopathy risk. Multivariable Poisson regression predicted the 10-year risk of cardiomyopathy (Common Terminology Criteria for Adverse Events grade ≥3: requiring heart failure medications or heart transplantation or leading to death) following baseline visit/survey. Model performance was assessed by area under the receiver operating characteristic curve (AUC).
resultsCardiomyopathy was clinically identified in 75 (2.2%, SJLIFE) and self-reported in 87 (1.3%, CCSS) survivors within 10 years of the baseline assessment. AUC of the clinical model with sex, age at cancer diagnosis, cumulative anthracycline, and mean heart radiation doses was 0.833 (SJLIFE) and 0.812 (CCSS). Age at baseline, hypertension, and genetic ancestry showed associations with higher cardiomyopathy rates in SJLIFE but did not increase AUC in CCSS (0.812). Adding PRSs for hypertrophic cardiomyopathy and left ventricular end-systolic volume improved AUC in CCSS (0.822; P = 0.016). Compared with existing survivorship-care guidelines, the PRS model classified fewer survivors as high-risk or moderate-risk, while identifying survivors in those categories as having 1.5-times greater risk.
conclusionsWe developed and validated models with highest-to-date performance for estimating the 10-year risk of cardiomyopathy in survivors of childhood cancer. Results could enhance identification of at-risk survivors beyond current guidelines.
