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
Background: Vulvar endometriosis is an exceptionally rare manifestation of extrapelvic endometriosis, particularly when located at the site of a prior episiotomy. Often misdiagnosed as more common vulvar pathologies, these lesions may present with cyclical pain and swelling, mimicking Bartholin's gland cysts or infected epidermal inclusion cysts. Case: We report the case of a 25-year-old gravida 3 para 2 woman with long-standing dysmenorrhea, dyspareunia, and a right vulvar mass that fluctuated with her menstrual cycle. Initially presumed to be a Bartholin's cyst, the lesion failed to respond to antibiotics and sitz baths. MRI revealed a complex vaginal wall cyst without classic signs of pelvic endometriosis. Examination under anesthesia and aspiration of chocolate-colored fluid raised suspicion for an endometriotic lesion. Surgical excision confirmed endometrial glands and stroma with hemosiderin-laden macrophages-consistent with vulvar endometriosis at the site of a right mediolateral episiotomy scar. Postoperative recovery was uneventful, and the patient experienced complete resolution of symptoms. Conclusion: This case highlights the diagnostic challenge of vulvar endometriosis in women with prior perineal trauma. Clinicians should maintain a high index of suspicion for endometriosis in cyclical vulvar masses-especially when located along episiotomy scars and unresponsive to conventional treatment. Early recognition and surgical excision can be curative and significantly improve quality of life.
