Outcome analysis of the surgical team in open surgical repair of intact abdominal aortic aneurysm surgery.

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
objectivesTo analyze how the experience of the surgical team went to impact the outcomes after open surgical repair (OSR) of intact abdominal aortic aneurysms (AAAs).
methodsThis is a single-center, observational cohort study with retrospective analysis of all OR for intact AAA performed between 1 January 2010 and 31 December 2022. The primary outcome was survival at 30 days and in follow-up, and a composite outcome of mortality and major complication. The secondary outcome was freedom from aorta-related reintervention. All outcomes were stratified according to the experience of the operating team (surgeons and anesthesiology).
resultsWe analyzed 103 (7.2%) patients: 97 (94.2%) males and 6 (5.8%) females. The mean age was 76 ± 8 years (range, 55-93). The best possible team composition was present in 52 (50.5%) interventions. The follow-up index was 0.82 ± 0.18 (range, 0.6-1.0). Mean follow-up duration was 59 ± 43 months (range, 0-158). We observed no differences between teams in major complications (best, 17.3% vs mixed, 21.6%; OR: 0.4, P = 0.622), 30 days mortality (best, 0% vs mixed, 5.9%; OR: 7.6, P = 0.118) and composite outcome (best, 11.5% vs mixed, 17.6%; OR: 0.8, P = 0.416). Cox regression analysis identified the best possible team as a protective factor against the need for reintervention (hazard ratio: 0.2; 95% confidence interval: 0.06-0.88, P = 0.032).
conclusionsIn our experience, OR of AAA yielded satisfactory results in terms of safety and efficacy independently of the team's experience. A more experienced team may protect against aorta-related reintervention.
