1 · What the graph read from it

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.

2 · The registry

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

backgroundMüllerian duct cysts (MDCs) are rare congenital anomalies. They arise from Müllerian duct remnant (MDR) and usually present as prostatic utricle cyst or pelvic mass. The authors report their experience with an extremely rare case of multiple intradural extramedullary MDCs. OBSERVATIONS: The patient, a 31-year-old female, presented with a 6-month history of progressive numbness, weakness, and sensory deficit in her lower extremities. After neurological examination at the authors' hospital, an MRI study was performed, revealing multiple intradural cystic lesions from C6 to L3, extending over 17 vertebral segments. Preoperative differential diagnoses included hydatid cysts, arachnoid cysts, enterogenous cysts, tuberculosis, and infection. Seven extramedullary noncommunicating transparent cysts were totally removed by surgery, with significant improvement of the neurological symptoms. Pathological examination showed MDCs. LESSONS: This is the first reported case of compressive myelopathy caused by multiple intraspinal subdural extramedullary MDCs. Regular imaging examinations and laboratory tests do not provide valuable information for differential diagnosis. Careful preoperative cyst localization and complete microsurgical resection are essential for a good outcome. https://thejns.org/doi/10.3171/CASE2511.
