Case of ossification of the ligamentum flavum causing cauda equina compression.
Article in Surgical neurology international, 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
Background: Ossification of the ligamentum flavum (OLF) is characterized by heterotopic bone formation within the ligamentum flavum. It typically causes progressive, chronic spinal canal stenosis, but only rarely acute cauda equina syndromes. Case Description: A 29-year-old patient presented with cauda equina syndrome characterized by saddle numbness, urinary incontinence, and bilateral foot drop. She underwent an urgent decompression for a disc herniation, at which time the surgeons encountered severe OLF, causing cauda equina compression. After performing a computed tomography scan to assess the extent of ossification, the patient was taken back to the operating room for completion of the original laminectomy with extension to an adjacent level. Her postoperative recovery was uneventful. Conclusion: Here, a 29-year-old presented with cauda equina syndrome attributed to a herniated lumbar disc and single-level OLF.
