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
Purpose: This study was conducted to evaluate the prevalence, causes, management strategies, and outcomes of secondary interventions after endovascular aneurysm repair (EVAR) in a Korean cohort. Methods: We retrospectively reviewed 242 patients who underwent standard EVAR for infrarenal abdominal aortic aneurysm at Seoul National University Bundang Hospital between 2008 and 2023. Clinical and anatomical parameters were analyzed. Secondary intervention indications, management, and outcomes were documented. Kaplan-Meier analysis estimated freedom from intervention and survival, and Cox regression identified predictors of mortality. Results: During a mean follow-up of 61.4 ± 45.8 months, 54 patients (22.3%) underwent 70 secondary interventions. The most common indications were Type II endoleaks with sac growth (24.1%), graft limb occlusion/stenosis (20.4%), Type IB endoleaks (11.1%), and Type III endoleaks (9.3%). Type II endoleaks were primarily treated with transarterial embolization, but many required repeated interventions or open conversion. Type I and III endoleaks were managed with stent graft extensions, endoanchors, or revision EVAR. Freedom from secondary intervention was 73.3% at 5 years and 57.5% at 10 years. Aneurysm-related survival was high (95.3% at 10 years), but overall survival declined to 42.5%, mainly due to comorbidities like malignancy, pneumonia, and cardiovascular disease. Multivariate analysis identified age, chronic obstructive pulmonary disease, hospital stay, and aneurysm diameter as independent mortality predictors, with dyslipidemia being protective. Conclusion: Secondary interventions after EVAR were required in over 20% of patients, primarily for Type II endoleaks. While aneurysm-related survival remained high, overall survival was limited by comorbidities. Lifelong imaging surveillance and management of comorbidities are essential for optimizing EVAR outcomes.
