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
Background: The association between case volume and outcomes in acute type A aortic dissection (ATAAD) repair is well established; however, the impact of elective proximal aortic surgery volume on emergent ATAAD repair outcomes remains unclear. Methods: Using the 2017-2020 Nationwide Readmission Database, we identified 22,700 elective proximal aortic repairs and classified hospitals into high-volume (median, 58 cases/year), medium-volume (median, 22 cases/year), and low-volume (median, 5 cases/year) groups. We analyzed 10,793 emergent ATAAD repairs performed at these hospitals. The primary outcome was in-hospital mortality. Secondary outcomes included stroke, renal failure necessitating dialysis, cardiac bleeding, respiratory failure necessitating ventilation, sepsis, vascular complications, and failure to rescue (FTR), defined as mortality occurring after any of these complications. Multivariable logistic regression assessed associations between hospital volume and outcomes. Results: Overall, 74.4% of ATAAD repairs occurred at low- or medium-volume hospitals. High-volume hospitals had greater ATAAD case volume (median, 25 vs 12 vs 5 cases/year; Conclusions: Higher elective proximal aortic surgery volume is independently associated with improved ATAAD outcomes. Concentrating elective volume and developing dedicated aortic teams may improve preparedness and outcomes.
