Isolated appendiceal endometriosis resulting in intussusception.
Article in Oxford medical case reports, 2018. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
An inverted (intussuscepted) appendix is a rare finding, often mistaken for a polyp as it presents with vague symptoms. This can result in misdiagnosis and inappropriate management. Diagnosis is usually made through surgery. Rarely, endometriosis has been found as the cause of the intussusception. A 42-year-old woman presented with frequent loose stools over 2 years, an elevated calprotectin over 400 μg/g faeces (normal <110) and a serum C-reactive protein of 40 mg/l (normal <5 mg/l). Endoscopy showed an inverted appendix. Histopathology results showed inflammation and ulceration. Laparoscopic appendicectomy was performed successfully, and endometriosis was found on the inverted appendix. This is the first case reported of an inverted appendix containing endometriosis, in which the intussusception of the appendix has been diagnosed on endoscopy. This case highlights how endometriosis can involve just the appendix, without any involvement of reproductive organs. We suggest considering inverted appendix as a differential diagnosis when investigating caecal lesions.
