1 · What the graph read from it

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.

2 · The registry

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

Background: Despite advances in technical and perioperative care, surgery for acute type A aortic dissection (ATAAD) carries significant morbidity and mortality. This study evaluated whether high-volume aortic surgeons independently improve perioperative and long-term outcomes compared to their low-volume counterparts. Methods: Patients who underwent surgery for ATAAD between 2011 and 2024 were identified. A high-volume surgeon was considered one who performed surgery for ATAAD on more than 10 patients annually. Patients were stratified into 2 groups based on the surgeon performing their operation, either a high-volume or low-volume aortic surgeon. Results: A total of 785 patients underwent ATAAD repair, including 715 (91.1%) performed by high-volume surgeons and 70 (8.9%) performed by low-volume surgeons. Preoperative demographics were similar in the 2 groups, although patients operated on by low-volume surgeons had a lower rate of malperfusion (9.9% vs 17.4%; Conclusions: High-volume surgeons were associated with superior early outcomes in ATAAD repair, including lower operative mortality, reoperation for bleeding, and ICU utilization, despite performing more complex procedures.
