A Case of Spontaneous Umbilical Endometriosis.
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
Umbilical endometriosis, also known as Villar's nodule, is an atypical manifestation of endometriosis. We present a rare case of spontaneous Villar's nodule in a young, nulliparous woman with no history of abdominal surgery or trauma who had no classic symptoms of endometriosis. Clinical examination revealed a painless umbilical nodule, and histopathologic evaluation demonstrated endometrial-type glands and stroma, confirming primary cutaneous endometriosis. Further gynecologic evaluation, including pelvic examination and transvaginal ultrasound, showed no evidence of pelvic endometriosis. We review proposed pathogenic mechanisms, discuss diagnostic considerations, and highlight the importance of prompt gynecologic referral. Early recognition with complete excision and appropriate gynecologic follow-up is essential, particularly in patients desiring future fertility.
