Risk factors of incisional hernia enlargement after colorectal cancer surgery: a retrospective, single-center study.

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
purposeIncisional hernia (IH) often develops during surveillance after colorectal cancer surgery, with repair sometimes delayed due to the risk of recurrence. This study aimed to identify the risk factors for IH enlargement by objectively measuring the changes in defect size.
methodsWe retrospectively analyzed 83 patients who developed IH after curative laparoscopic colorectal surgery at the Osaka Rosai Hospital between 2017 and 2021. Computed tomography was used to measure the IH defect sizes at diagnosis and at the end of the surveillance. Univariate and multivariate analyses were performed to determine the risk factors for enlargement.
resultsThe median IH defect size increased from 23.7 to 32.7 mm over a median follow-up of 1003 days. The highest quartile of defect size change was 12.1 mm and was used to classify patients into stable and enlarged IH groups. A multivariate analysis revealed that a high body mass index (≥ 25 kg/m
conclusionsObesity, early IH development, and systemic inflammation are associated with IH progression. Careful monitoring of patients with these risk factors is warranted.
