Reinfection incidence following surgical intervention for infected aortic bypass: a meta-analysis.
Synthesis in European journal of clinical microbiology & infectious diseases : official publication of the European Society of Clinical Microbiology, 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
backgroundInfection of vascular grafts after aortic revascularization surgery is a serious complication with high morbidity and mortality. This systematic review and meta-analysis aims to determine reinfection incidence in patients undergoing surgical intervention for infected aortic bypass grafts and identify key risk factors in the literature. MATERIALS AND
methodsThis systematic review and meta-analysis followed PRISMA guidelines. Three electronic databases, PubMed/MEDLINE, Scopus, and Web of Science were used to search studies published after January 1, 2000, that assessed reinfection rates following surgical intervention for infected aortic bypass grafts. Random-effects meta-analysis was performed to calculate pooled incidence of major outcomes.
resultsOur systematic review included 30 studies with a total of 2,341 patients. Overall reinfection rate was 12.7% (95% CI: 8.6%-16.9%). In terms of morbidity 34.1% had acute kidney injury, 23.8% needed amputation, and 29.4% developed acute limb ischemia. The 30-day mortality rate was 27.8% (95% CI: 13.2%-42.4%).The medical approach to treatment varied significantly, however, the majority involved total removal of the infected prosthesis. The main microorganisms isolated in primary infections were mostly Staphylococcus and Enterococcus species, with a notable representation of gram-negative bacteria.
conclusionReinfection rates after surgical treatment of infected aortic bypass grafts were relatively high and constitute a challenge of high clinical impact. This is further demonstrated by the high 30-day mortality rate. The significant variation in treatment approaches observed above also highlights the lack of formalized management protocols. Further studies are needed to determine the best surgical approach and patient-related risk factors to optimize outcomes in this difficult population.
