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
backgroundNeonatal and infant aortic arch reconstruction remains a high-risk cardiovascular procedure requiring effective cerebral and myocardial protection. Variability in perfusion strategies may influence early hemodynamic stability and postoperative recovery. This study aimed to evaluate the early and short-term cardiovascular outcomes of a standardized beating-heart aortic arch reconstruction strategy incorporating simultaneous antegrade selective cerebral and continuous coronary perfusion.
methodsIn this retrospective single-center cohort study, 31 consecutive neonates and infants undergoing aortic arch reconstruction between November 2022 and December 2025 were analyzed. A standardized surgical protocol was applied, consisting of extensive ductal tissue resection, interdigitating posterior end-to-end anastomosis, anterior autologous pericardial patch augmentation, and moderate hypothermic antegrade selective cerebral perfusion combined with continuous coronary perfusion via innominate artery cannulation. Early postoperative outcomes and short-term echocardiographic follow-up results were assessed.
resultsThe cohort included 31 patients, 22.6% of whom had complex associated cardiac anomalies requiring concomitant procedures. Median cardiopulmonary bypass and aortic cross-clamp times were 119 and 64 min, respectively. There was no in-hospital mortality. Major complications were infrequent, and median intensive care unit stay was 5 days. During a median follow-up of 6.8 months, one patient (3.2%) developed recoarctation requiring reintervention. No late mortality was observed.
conclusionsA fully standardized beating-heart aortic arch reconstruction strategy incorporating simultaneous cerebral and coronary perfusion demonstrated favorable early cardiovascular and short-term outcomes, even in anatomically complex cases. Preservation of continuous coronary perfusion may be associated with improved myocardial stability and early postoperative recovery; however, these findings should be interpreted as observational and hypothesis-generating given the absence of a control group. Larger multicenter studies with longer follow-up are warranted to confirm these findings.
