The Clinical Impact of Concomitant Hemi-Arch Reconstruction at the time of Aortic Root Replacement.

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
Objective: The significance of concomitant hemi-arch aortic reconstruction in the setting of aortic root replacement is largely unknown. In this first multi-institutional study, the clinical impact of concomitant hemi-arch aortic reconstruction at the time of aortic root replacement was reviewed. Methods: From 2004 to 2021, 1869 patients underwent aortic root replacement and ascending aorta replacement at 2 major academic centers: 1116 with concomitant hemi-arch aortic reconstruction (aortic root replacement/hemi-arch aortic reconstruction) and 753 without hemi-arch aortic reconstruction (aortic root replacement/ascending aorta). Procedure and propensity score matching resulted in 698 pairs, which were compared. The primary end point was in-hospital mortality. Results: Mean age at operation was 56.8 ± 14.7 years and similar between groups ( Conclusions: Clinical outcomes after both aortic root replacement/ascending aorta or with concomitant hemi-arch aortic reconstruction are excellent. Concomitant hemi-arch aortic reconstruction was associated with a higher rate of postoperative stroke and in-hospital mortality. The decision to perform hemi-arch aortic reconstruction at the time of aortic root replacement should be considered carefully and must be individualized in a patient-specific manner for optimal outcomes.
