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
objectivesExtracorporeal membrane oxygenation is widely used to treat cardiopulmonary failure after congenital heart surgery. This study evaluated patient characteristics, outcomes, and risk factors associated with perioperative veno-arterial extracorporeal membrane oxygenation use.
methodsAll patients undergoing congenital heart surgery between 2001 and 2024 at our centre were included. Prevalence, outcomes, risk factors for extracorporeal membrane oxygenation support, and predictors of in-hospital mortality following extracorporeal membrane oxygenation were analysed.
resultsAmong 9892 congenital heart operations, extracorporeal membrane oxygenation was required in 178 (1.8%) patients for a median of 6 days (interquartile range 4-9). Median age and weight at surgery were 2.8 months (interquartile range 0.4-25.2) and 4.1 kg (interquartile range 3.2-8.9), respectively. In patients ≤2 years, the Norwood procedure and surgery for coronary artery malformations were independent risk factors for extracorporeal membrane oxygenation support. Successful weaning was achieved in 62% (n = 111), while 17% (n = 30) required a second extracorporeal membrane oxygenation run. In-hospital mortality after extracorporeal membrane oxygenation was 55% (n = 98), occurring a median of 16 days (interquartile range 5-34) after surgery; 27% of the patients died after a successful first weaning. Model-based predictions showed an 8-fold increase between days 6 and 12 of extracorporeal membrane oxygenation support, with predicted mortality rising from 26% to 74%.
conclusionsApproximately 2% of patients undergoing congenital heart surgery require extracorporeal membrane oxygenation support with an overall survival rate of around 50%. Prolonged extracorporeal membrane oxygenation duration and acute renal failure requiring renal replacement therapy were independently associated with mortality. The sharp increase in mortality beyond 6 days of extracorporeal membrane oxygenation highlights the need for early reassessment of reversibility and timely consideration of alternative strategies.
