Extended aortic coverage in thoracic aortic endovascular repair is not associated with spinal cord ischemia.
Article in JTCVS open, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Spinal cord ischemia (SCI) after thoracic endovascular aortic repair (TEVAR) remains a debilitating complication, occurring in 10% of patients. Studies have shown that extended aortic coverage is a risk factor for SCI. This study evaluates whether extended aortic length coverage is a significant risk factor for SCI. Methods: This study retrospectively reviewed 277 consecutive patients who underwent TEVAR successfully between 2006 and 2021 at a single institution. The patients were classified into 2 groups: ≥205 mm and <205 mm of thoracic aortic coverage. Analysis of variance was used to compare these variables and associated aortic coverage between the 2 groups. Univariable logistical regression was used to compare SCI and associated factors. Results: Of the 269 patients who underwent successful TEVAR, 127 (47.2%) had ≥205 mm and 142 (52.8%) had <205 mm of aorta coverage. Patients with ≥205 mm of thoracic aorta coverage were more likely to be smokers ( Conclusions: Extended aortic coverage (compared with the standard approach) was not associated with a higher risk of SCI; however, this may have been mitigated by a higher prevalence of prophylactic lumbar drainage in this population.
