Prognostic Factors Associated With Early Recovery From Veno-Arterial Extracorporeal Membrane Oxygenation Support in Patients With Fulminant Myocarditis.
Article in Journal of the American Heart Association, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
backgroundFulminant myocarditis is life-threatening and often requires mechanical circulatory support. Predicting its clinical course is crucial, yet data on early recovery predictors, particularly with veno-arterial extracorporeal membrane oxygenation, remain lacking. METHODS AND
resultsWe aimed to identify prognostic factors of early recovery in fulminant myocarditis requiring veno-arterial extracorporeal membrane oxygenation by retrospective analysis of a nationwide registry in Japan. Early recovery was defined as successful weaning from mechanical circulatory support within 7 days and discharge without heart transplantation or long-term mechanical circulatory support. A total of 343 patients were analyzed; 71 were classified as early recovery and 272 as nonearly recovery. The early recovery group was significantly younger, had higher white blood cell counts, and lower creatine kinase-myocardial band level than the nonearly recovery group. To enhance clinical interpretability, we dichotomized continuous variables using optimal cutoff values derived from the Youden index. Multivariable logistic regression analysis showed the independent factors of early recovery were age ≤40 years (odds ratio [OR], 3.25), white blood cell count ≥11 000/μL (OR, 3.10), and creatine kinase-myocardial band ≤61 U/L (OR, 2.46), and if all conditions were fulfilled, the early recovery rate increased to 61.5%. Additionally, although not statistically significant, the number of rehospitalization with cardiovascular causes, death, or heart transplantation at 1-year follow-up was higher in the nonearly recovery group.
conclusionsOur study suggested younger patients who have a strong inflammatory response but less myocardial damage on admission could recover earlier. Conversely, in cases where mechanical circulatory support duration is prolonged, careful monitoring is required for prolonged left ventricular dysfunction and subsequent prognosis.
