Incidence and microbiological etiology of vascular graft and endograft infections: a systematic review and meta-analysis.
Review in Infection, 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
purposeVascular graft and endograft infections (VGEIs) represent rare but severe complications following abdominal aortic aneurysm (AAA) repair. Reported incidence rates vary widely, and comparative estimates between surgical procedures remain limited.
methodsA systematic search was performed in PubMed and Scopus. The search covered human studies published up to 3rd May 2025. The protocol was conceived in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) 2020 guideline. it was registered in PROSPERO (registration number CRD42024525824) on 18th March 2024.
resultsNineteen studies were included. The pooled incidence of infective events was 0.36 per 100 person-years (95% CI 0.21-0.64; I² = 93.3%) after endovascular aneurysm repair (EVAR) and 0.60 per 100 person-years (95% CI 0.22-1.60; I² = 96.3%) after open surgery (OS). In EVAR-related VGEI, Staphylococcus spp. were the most frequently reported pathogens (5 cases, 12.5%). Polymicrobial etiology was not infrequent (5 cases, 12.5%), and a high proportion of infections were culture-negative (18 cases, 45.0%). In OS, data did not permit an etiological analysis. In mixed-procedure studies, fungal infections (16 cases, 17.8%), Gram-negative bacteria (15 cases, 16.7%), and polymicrobial infections (14 patients, 15.6%) were frequently reported. Considerable heterogeneity across the included studies, particularly regarding the diagnostic criteria used to define VGEI, was identified. Univariable meta-regression analyses did not identify significant associations between incidence rates and study-level covariates, including mean age, sex distribution, or year of publication.
conclusionVGEIs remain uncommon but relevant complications after AAA repair, with a lower incidence after EVAR than after OS. Future studies should prioritize standardized diagnostic criteria and detailed etiological reporting to improve epidemiological and clinical understanding.
