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
objectivesDespite the increasing use of the en bloc rotation of the outflow tracts to treat patients with transposition of the great arteries with left ventricular outflow tract obstruction, long-term outcome data are scarce. Cases with simultaneous Mustard operation are a challenging technical expansion. This retrospective study aims to evaluate long-term outcomes in a single-centre cohort.
methodsAll patients undergoing the en bloc rotation at the Children's Heart Center Linz between 2003 and 2024 were retrospectively analysed.
resultsThe en bloc rotation was performed in 38 patients. Median age at operation was 4.1 (0.7; 23.9) months, weight 5.4 (3.7; 9.6) kg. A congenitally corrected transposition was present in 3 patients, in which a simultaneous Mustard procedure was performed. Median cardiopulmonary bypass time was 291 (270; 353) minutes, aortic cross-clamp time 160 (142; 185) minutes. The pulmonary valve could be preserved in 24 children (63%). Two patients died during the hospital stay (5%). During a follow-up period of median 9.3 (4.4; 14.3) years, 3 further children deceased, 5 surgical reinterventions were necessary. There was no death or surgical reintervention in the congenitally corrected transposition group.
conclusionsThe long-term outcome of the en bloc rotation is very promising, as could be expected due to the anatomic repair with growth potential in all tubular structures. The increased experience also with the Mustard operation allowed the combination of both complex procedures with excellent short-term outcome.
