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

backgroundBiologic implants have been recommended for reinforcement in routine and challenging hernia repair. However, experimental and clinical studies have reported adverse effects (e.g., slow implant integration and pronounced foreign body reaction). To evaluate the impact of different material processing methods (cross-linking vs. non-cross-linking of collagen) and implant design, four different biologic hernia implants were compared directly in experimental intraperitoneal onlay mesh plasty (IPOM). Tissue integration, shrinkage, and foreign body reaction were primary outcome parameters.

methodsIn this study, 48 Sprague-Dawley rats were randomized to four treatment groups. Open IPOM repair was performed. One peritoneal defect per animal was covered with 2 × 2 cm patches of cross-linked or non-cross-linked implants including CollaMend (n = 12), Peripatch (n = 12), Surgisis (n = 12), and Tutomesh (n = 12). In half of the animals, fibrin sealant was applied for additional fixation and to cover sutures. The observation period was 60 days. The primary outcome parameters were implant integration, shrinkage, and foreign body reaction. Macroscopic and histologic assessments were performed.

resultsThe integration of implants was insufficient in all the groups. The implants could be detached easily from the underlying tissue, and the penetration of fibroblasts and vessels was limited to the perforations. Foreign body reaction was pronounced with CollaMend and Surgisis, leading to persistent granulomatous inflammation. Shrinkage was excessive with Surgisis, whereas Tutomesh and Peripatch yielded sufficient anti-adhesion and elicited no foreign body reaction.

conclusionAt 2 months, cross-linked and non-cross-linked biologic hernia implants were poorly integrated. Cross-linking led to a more pronounced foreign body reaction. Less inflammatory response may reduce local complications, but did not enhance implant integration in this study.
