Predictive model for recurrence of incisional hernia constructed by CT abdominal wall imaging features.
Article in BMC 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
backgroundThe recurrence rate after incisional hernia surgery is the most important concern for patients and surgeons, which not only causes pain to the patient but also adds additional medical costs. This study aims to investigate CT imaging features based on abdominal wall mechanics for recurrence after incisional hernia surgery. MATERIALS AND
methodsWe collected data from patients who were diagnosed with incisional hernia and underwent hernia repair from January 2017 to January 2022 in Shanxi Provincial People's Hospital. Based on Laplace's equation, an equation for spherical wall pressure, we further measured the preoperative abdominal wall thickness and abdominal wall radius of the patients by CT and measured the abdominal wall muscle area and visceral fat area at the third lumbar level by using Slice-O-Matic 5.0 software, and the sarcopenia index was further obtained by dividing the muscle area by the square of the height. Then, we analyzed their relationship with the postoperative recurrence of incisional hernia.
resultsBy univariate and multifactorial analyses, we found that excessive visceral adiposity, high BMI and sarcopenia were independent risk factors for incisional hernia recurrence. In further stratified analysis, we also found that patients with combined sarcopenia had a higher probability of recurrence. Our results found that visceral fat was a higher risk factor for incisional hernia recurrence than BMI.
conclusionThis study was a retrospective study. Based on the Laplace equation, sarcopenia and visceral fat are independent risk factors for recurrence after incisional hernia.
