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
purposeThis study aimed to compare outcomes of the modified wrapping technique (MWT) and supracoronary tube replacement (STR) for isolated ascending aortic aneurysms, focusing on perioperative safety, 5-year survival, and arterial stiffness.
methodsThis retrospective, single-center study included 205 patients undergoing MWT (n = 91) or STR (n = 114) between 2006 and 2019 for isolated ascending aortic aneurysms ≥50 mm or rapidly progressing lesions. A prospective substudy evaluated arterial stiffness using the SphygmoCor system in a matched subgroup of 40 patients. The primary endpoint was 5-year survival; secondary endpoints included perioperative outcomes, prosthetic infection, and hemodynamic indices.
resultsMWT showed significantly shorter cardiopulmonary bypass and aortic cross-clamp times (p <0.0001) and reduced hospital stay (10.5 ± 0.3 vs. 13.5 ± 0.8 days; p = 0.001). In-hospital mortality tended to be lower with MWT (0% vs. 4.4%; p = 0.06). Five-year survival was comparable between groups (88.1% vs. 83.4%; p = 0.17). Prosthetic infection was significantly lower in the MWT group (1.1% vs. 7.0%; p = 0.04). Hemodynamic assessment demonstrated lower pulse wave velocity and aortic augmentation index in the MWT group.
conclusionsMWT was associated with shorter operative times and lower prosthetic infection rates while maintaining similar early and mid-term survival compared with STR. These findings suggest MWT as a valuable alternative in selected patients.
