Colon Cancer Presenting as an Incarcerated Incisional Hernia: A Case Report.
Article in Cureus, 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
Colorectal cancer within a hernia sac is rare. Although cases involving inguinal hernias have been reported, colorectal cancer in an incisional hernia has not been documented. A 91-year-old woman with a history of cholecystectomy 30 years earlier presented with melena, hematemesis, and anorexia. CT showed an incisional hernia at the right subcostal region containing the ascending colon with wall thickening and fat stranding, raising concern for incarceration and possible malignancy. Emergency laparotomy revealed an incarcerated ascending colon with a type 2 adenocarcinoma. Right hemicolectomy and primary hernia repair were performed. Histopathology confirmed pT4aN0M0 adenocarcinoma with venous congestion but no tumor rupture or worsening of lymphovascular invasion. The patient was discharged on postoperative day 22. This appears to be the first reported case of colorectal cancer in an incisional hernia. Occult malignancy should be considered in elderly patients with complicated incisional hernias, and early surgery is advisable for irreducible cases.
