Incidence and risk factors for recurrence of incisional hernia repair after liver transplantation: a retrospective cohort study.
Article in Hernia : the journal of hernias and abdominal wall surgery, 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
purposeThe objective of this study was to evaluate the incidence and identify risk factors associated with the recurrence of incisional hernia (IH) following initial parietal repair in patients who had undergone liver transplantation. Liver transplantation (LT) is a complex procedure associated with numerous complications, particularly those affecting the abdominal wall, with incisional hernia (IH) being the most significant. To date, the risk factors contributing to IH recurrence in this population have not been systematically assessed.
methodsThis retrospective, single-center study included all patients who underwent liver transplantation at Rennes University Hospital between January 1, 2012, and December 31, 2018. The list of eligible patients was provided by the French Biomedicine Agency.
resultsA total of 803 liver transplant recipients were included. Among them, 282 patients (35.1%) developed an incisional hernia (IH) after a median follow-up of 75.87 months [54.7-97.2]. Of these, 50 patients (35.4%) experienced IH recurrence at a median interval of 8.8 months [5.2-34.2] following primary repair. Identified risk factors for recurrence included: length of hospital stay after the initial repair (HR: 1.09 [1.09-1.13], P = < 0.0001), type of repair (suture versus prosthetic) (HR: 2.48 [1.25-4.9], P = 0.009). Visceral obesity is considered a high-risk factor (HR: 2.21 [0.98-4.95], P = 0.055), although the association no longer reached the conventional threshold for statistical significance."
conclusionTo the best of our knowledge, this is the first study to assess body composition as a risk factor for incisional hernia recurrence in the liver transplant population. These findings highlight the importance of considering visceral obesity as a significant predictor of recurrence.
