1 · What the graph read from it

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.

2 · The registry

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

backgroundPort-site hernias are a recognized complication of minimally invasive surgery, particularly occurring when large trocars are employed. Although fascial closure is crucial for preventing port-site hernias, achieving closure can be technically challenging, especially in overweight or obese patients. Recently, a 12-mm port featuring an integrated fascial closure system has been introduced, but its clinical safety and efficacy have not been thoroughly assessed.

methodsThis was a multicenter, prospective observational cohort study. We enrolled patients undergoing laparoscopic or robot-assisted surgery in which the VersaOne™ Fascial Closure System (Medtronic, Minneapolis, MN, USA) was utilized for a 12-mm port. Specifically, patients with an abdominal wall thickness of ≥ 30 mm were included. The primary outcome was the incidence of port-site hernias at 6 months postoperatively, confirmed through CT imaging and clinical examination. Secondary outcomes included closure time, intraoperative bleeding, infection, collateral organ damage, hospital readmission, and reoperation. Complications were graded according to the Clavien-Dindo classification.

resultsAmong 103 patients (median body mass index, 27.1 kg/m

conclusionsThe VersaOne™ Fascial Closure System appears to be a safe and efficient method for fascial closure in minimally invasive surgery. Its use was particularly beneficial in patients with thick abdominal walls. Further randomized controlled studies are warranted to comprehensively validate these findings.
