Association between Changes in Stent Graft Volume and Type II Endoleaks after Endovascular Aneurysm Repair.

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
Objectives: Type II endoleaks (T2ELs) after endovascular aneurysm repair (EVAR) are associated with delayed adverse events. This study evaluated the association between changes in stent graft volume (SgV) and T2EL after EVAR. Methods: This study included 127 patients who underwent EVAR for abdominal aortic aneurysms between 2010 and 2022. SgVs were calculated using computed tomography, and SgV ratios were calculated by dividing SgV 2 years after EVAR by SgV immediately after EVAR. The association between the SgV ratio and T2EL 2 years after EVAR was evaluated. Results: T2ELs were detected in 62 patients (49%) 2 years after EVAR. Univariate analysis revealed that age, number of patent lumbar arteries, expanded polytetrafluoroethylene (ePTFE) stent grafts, and the SgV ratio were significantly correlated with T2EL. Multivariate analysis showed that age ≥80 years, patent lumbar arteries ≥4, ePTFE stent graft, and SgV ratio ≤1.23 were independently associated with T2EL. In both the ePTFE (80 patients) and polyester (47 patients) stent graft groups, the SgV ratio was independently associated with T2EL. Conclusions: The SgV ratio was significantly correlated with T2EL and may improve T2EL surveillance after EVAR.
