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
objectivesTo identify factors associated with the development of death by neurologic criteria (DNC) in neonates treated with extracorporeal membrane oxygenation (ECMO).
designRetrospective registry study.
settingData reported to the Extracorporeal Life Support Organization registry from 2010 to 2023. PATIENTS: Neonates (≤ 28 d old) who were supported with ECMO, excluding those born before 37 weeks' gestation or with missing gestational age data. The final cohort comprised 14,970 neonates.
interventionsNone. MEASUREMENTS AND MAIN
resultsDNC occurred in 70 neonates in the cohort (0.5%), accounting for 2% of overall mortality rate. Pre-ECMO factors associated with greater relative risk ratio (RRR) of DNC included pre-ECMO cardiac arrest (RRR, 2.64), pH less than 7.08 (25th percentile: RRR, 2.06), and cardiac support type (RRR, 2.04). On-ECMO, factors independently associated with DNC included pH less than 7.35 (25th percentile: RRR, 2.76), Pa o2 greater than 162 mm Hg (75th percentile: RRR, 2.75), and central cannulation (RRR, 2.36). We failed to identify an association between relative change in Pa co2 greater than 50% and DNC, but it correlated with other causes of death. Most DNC diagnoses (84%) occurred after 24 hours of ECMO.
conclusionsDNC is rarely diagnosed in neonatal ECMO cases. Both pre-ECMO and on-ECMO factors associated with DNC included pre-ECMO cardiac arrest, severe metabolic acidosis, and cannulation type. These findings underscore the importance of optimizing pre-ECMO and on-ECMO management and may indicate certain modifiable risk factors such as optimization of cardiopulmonary resuscitation and hyperoxia. Future research should explore preventive strategies and interventions to mitigate the risk of DNC in neonates receiving ECMO.
