Primary umbilical endometriosis: Surgical case report.
Article in JRSM open, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It has been retracted, and should not be counted. Cited by 3 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
Introduction: Endometriosis is a benign nevertheless a chronic condition which impacts greatly the quality of life through cyclic discomfort. We aim to report the case of umbilical endometriosis and a literature review of the different treatment modalities. Case Report: This was a case of a 43-year-old woman, with no history, who presented with a painful hemorrhagic umbilical swelling during the menstrual period associated with dysmenorrhea. Abdominal ultrasound revealed a subcutaneous umbilical mass of non-vascularized tissue nature confirmed on Doppler. Pelvic MRI which confirms the diagnosis of primary umbilical endometriosis. The patient underwent wide local excision of the endometriotic nodule with umbilical reconstruction. Histology confirmed the diagnosis of umbilical endometriosis. Resection margins were clear. Discussion: Extra-pelvic endometriosis sites are not common, especially the umbilicus. It usually occurs secondary to surgical scars, specifically after laparoscopy or open abdominal surgery. Surgical management is currently described as gold standard. Laparoscopic approach is recommended as it allows better visual inspection for secondary localization of endometriosis. Medical management corresponds to combined oral contraceptives (COCs) or progestins for management of endometriotic implants decreasing inflammatory effects, or Gonadotropin-releasing hormone for long-course treatment. Malignant transformation of the umbilical nodule has been described in literature with a reported risk of malignant transformation to be 3%. Conclusion: Current management of extragenital endometriosis suggest radical surgery with wide local excision. Due to the rarity, there is a paucity of data on umbilical endometriosis and mostly reported from case reports.
