Long-term Clinical Outcomes after Endovascular Treatment by Aortoiliac Artery Stent Implantation.
Article in Journal of atherosclerosis and thrombosis, 2026. 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
aimThe long-term clinical outcomes of endovascular therapy (EVT) for aortoiliac (AI) artery lesions remain unclear. This study aimed to investigate 10-year patency and mortality after AI stent implantation.
methodsThis multicenter retrospective study included 1919 patients (2375 limbs) who underwent AI stent implantation to treat symptomatic peripheral artery disease (PAD) between January 2005 and December 2010. The study outcome was primary patency, which was defined as a treated vessel without restenosis, mortality, and associated factors.
resultsThe mean age of the study cohort was 71±9 years. Chronic limb-threatening ischemia (CLTI) accounted for 17.2% of cases, and chronic total occlusion (CTO) was found in 24.6% of cases. During a median follow-up period of 2.9 years (interquartile range: 1.0-6.0 years), 412 patients lost patency, whereas 467 patients died without experiencing loss of patency. At 1, 6, and 10 years post-EVT, respectively, the primary patency rates were estimated to be 92.8%, 79.3%, and 77.2%, and the survival rates were 94.9%, 77.0%, and 63.1%. Female sex, CTO, and the presence of outflow lesions were significantly associated with an increased risk of patency loss after stent implantation (all P＜0.05), whereas age, dialysis-dependent renal failure, heart failure, and CLTI were significantly associated with an increased risk of mortality.
conclusionStent implantation for AI lesions achieved favorable 10-year patency, with patency loss plateauing after six years. No AI lesion characteristic was associated with mortality. These results support the long-term efficacy of EVT in the clinical practice.
