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
backgroundIncisional hernia (IH) is an important surgical complication that has several ways of prevention, including modifications in the surgical technique of the initial procedure. Its incidence can reach 69% in high-risk patients and long-term follow-up. Of the risky procedures, open abdominal aortic aneurysmectomy is the one with the highest risk. Ways to reduce this morbid complication were suggested, and prophylactic mesh rises as an important tool to prevent recurrence.
methodsA retrospective cohort study review of medical records of patients undergoing vascular surgery for abdominal aortoiliac aneurysm (AAA) or vascular bypass surgery due to aortoiliac occlusive disease. We identified 193 patients treated between 2010 and 2020. We further performed a one-to-nine matching analysis between the use of prophylactic mesh and control groups, based on estimated propensity scores for each patient.
resultsProphylactic mesh group had a 18% lower risk of IH, compared with the control group (relative risk: 0.82; 95% confidence interval [CI] = 0.74-0.93). The difference in IH rates between the groups compared was 2.6% (95% CI: -19.8 to 25.5). From the perspective of the number needed to treat, it would be necessary to use prophylactic mesh in 39 (95% CI: 35-44) patients to avoid one IH in this population.
conclusionUse of prophylactic mesh in the repair of AAA significantly reduces the incidence of IH in nearly one in five cases. Our data suggest that there is benefit in the use of prophylactic mesh in open aneurysmectomy surgery regarding postoperative IH development.
