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: Thoracic endovascular aortic repair (TEVAR) in Zone 2 frequently necessitates coverage of the isolated left vertebral artery (ILVA), a congenital vascular anomaly, to ensure adequate proximal sealing. However, the clinical requirement of ILVA revascularization remains uncertain. Thus, this study aimed to compare the outcomes between ILVA coverage and fenestration during Zone 2 TEVAR. Methods: We retrospectively analyzed the clinical records of patients with ILVA who underwent Zone 2 TEVAR between September 2010 and August 2023. Patients were divided into two groups: Coverage Group (n = 23) and Fenestration Group (n = 33). Baseline characteristics, surgical outcomes, and changes in left and right vertebral artery diameters pre- and postoperatively were compared. Continuous variables were compared using Student's Results: The overall cohort had a mean age of 54.48 ± 10.31 years, with 89.29% of participants male and a mean body mass index (BMI) of 25.88 ± 3.5 kg/m Conclusions: Fenestration is associated with a lower incidence of postoperative ILVA diameter reduction compared with direct coverage during Zone 2 TEVAR. These findings highlight the potential benefit of ILVA revascularization and underscore the need for further validation in larger studies.
