Chronic inflammation following hernia repair and cancer risk: A nationwide study.
Article in Surgery open science, 2025. 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
Purpose: Implantation of mesh in patients undergoing hernia surgery or prolonged inflammation due to postoperative complication may be associated with increased risk of cancer.We aim to test whether implementation of mesh or complicated postoperative course with readmittance was associated with increased risk of cancer. Methods: This register-based nationwide observational cohort study included 48,392 and 127,756 patients undergoing ventral and inguinal hernia surgery, respectively, during 1996-2004, with follow-up until Dec. 2014. In total, 16,909 patients undergoing ventral hernia repair with mesh, and 31,483 undergoing sutured repair, as well as 106,342 patients undergoing inguinal hernia repair with mesh and 21,414 undergoing sutured repair were included. Patients were matched with a reference cohort from the general Danish population and were followed in the Danish Cancer Registry. Results: For ventral hernia surgery, there was a significant association between mesh repair and risk of cancers, [(vs general population), HR 1.09 (95%CI, 1.00-1.18)]. Thirty-day readmission after mesh and sutured repair was associated with developing cancer [HR 1.15 (0.99-1.34) and 1.14 (1.00-1.31), respectively]. However, the association for suture repair (HR 1.14) did not reach statistical significance ( Conclusion: Patients undergoing ventral hernia repair with mesh and patients readmitted after inguinal or ventral hernia repair may have higher risk of developing cancer than the general population.These exploratory findings do not establish causality, but the association warrants further investigations in other populations.
