The Effectiveness of Anti-Adhesion Barriers on Prevention of Postoperative Adhesive Bowel Obstruction: Disease-Free Survival Analysis.
Article in Annals of gastroenterological surgery, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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: Anti-adhesion barriers are effective in reducing adhesion formation, but their impact on preventing adhesive bowel obstruction remains unclear. This study aimed to evaluate the effectiveness of anti-adhesion barriers in preventing adhesive bowel obstruction using a nationwide medical database in Japan. Method: Surgical cases for abdominal gastroenterological cancers were categorized into six categories based on procedure type (Open or Laparoscopic) and target organ (Stomach, Colorectum, and Hepatobiliary-pancreas). Patients were classified into an anti-adhesion barriers group (treatment) or a non-anti-adhesion barriers group (comparison). Propensity score matching was performed to balance baseline characteristics. Survival analysis with hospitalizations due to adhesive bowel obstruction as the outcome was conducted, and hazard ratios (HR) were calculated using univariate Cox regression analysis. Results: A total of 163 194 cases were analyzed. In the Open Colorectum and Laparoscopic Colorectum categories, the cumulative incidence curve for the treatment group was lower than that of the comparison group (Log-rank test; Open Colorectum: Conclusion: This study suggests that anti-adhesion barriers use could effectively reduce the risk of adhesive bowel obstruction in Open Colorectum and Laparoscopic Colorectum surgeries, but not in Open Stomach, Open Hepatobiliary-pancreas, or Laparoscopic Stomach surgeries. Further research is needed to confirm these findings and explore broader applications.
