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
Background: Endoluminal vacuum therapy has been experimentally used in patients with esophageal, rectal, and Roux-en-Y bypass surgery. Yorkshire pigs are good animal models for studying the safety and efficacy of endoluminal vacuum therapy and prior studies have employed these devices in rectal anastomotic defects, as rescue therapy for early anastomotic leaks, as well as prophylactic therapy as a means of protecting high risk anastomosis. Aim: The objective of this study is to assess the effects of a prophylactic vacuum assist device on bowel tissue surrounding an intact anastomosis at 30 days post device removal. Methods: A total of seven pigs underwent a rectal resection with primary anastomosis: five experimental pigs with a prophylactic endoluminal vacuum device in place for 5 days post-surgery and two control pigs with no device. All animals were euthanized on the 35 Results: No significant difference in inflammation or strictures was observed between the anastomosis of animals with the endoluminal vacuum devices and controls. Conclusion: We, therefore, conclude that endoluminal vacuum therapy is safe for prophylactic use in pigs undergoing low anterior resection and does not cause significant strictures. Relevance for Patients: Anastomotic leak is a feared complication resulting in increased costs, length of stay, and emotional distress. Endoluminal negative pressure vacuum therapy is a new technology that has been used in experimental models in both animals and humans for prevention and treatment of anastomotic leak. In this series we demonstrate endoluminal vacuum therapy is safe in a porcine model and does not result in stricture or increased adhesion formation. We expect endoluminal vacuum therapy to become more widely used in the future in both prevention and treatment of anastomotic leaks.
